Professor Sanjeev Kumar Aggarwal

Prof SKA was one of my favorite teachers. His sad demise at such an early age has come as a shocking news. He will always be remembered for his warmheartedness. May his soul rest in peace.

I am shocked to hear this - he was gem of a person. My heart goes out Madam and Keshav and his sister.

Prof. Sanjeev Aggarwal was one of the best teachers and persons I have ever met. He had guided and supported me through all the ups and downs of my PhD. Losing a father figure like him is an irreparable loss. May the God almighty provide courage to his family members. Sir, you will live on forever in our hearts and memories.

This is a socking sad news. I remember him meeting few times whenever I visited Campus. May his soul rest in peace and God give strength to his family to bear this loss. --Prem Mohan B.Tech(CS) - 83

Sudden and sad demise of Prof. Sanjeev Aggarwal (Professor and renowned scientist, Department of Computer Science and Engineering, IIT Kanpur) is a great loss to our CSE department, IIT Kanpur, India and entire world. This is an irreparable loss and can never be recuperated. He provided me His valuable comments on my research work and had a fatherly helping attitude. There was a divine poise on His face which made me forget my nervousness and exam fear. He was a Great Professor and a Great Human Being. We all are missing Him. He shall always remain alive in our hearts. May God give strength to His bereaved family. May His soul rest in peace in God's Kingdom.

I convey my heartfelt condolences to the family. My wife and I fondly recall our sabbatical year at the CSE Dept. of IITK. Warmth of the faculty and their families and especially that of Sanjeev are still fresh in our minds after more than 10 years. May his Jeeva rest in Peace. Kalpana and Kishor Trivedi

I  am shocked to hear this news. Prof. Aggarwal was one of the best teachers and mentors I have met. May his soul rest in peace and God give strength to his family in this difficult time.

So sad, so sudden! I remember him from his Pune days (which were also my own Pune University days) and subsequently so many occasions at IITK. Never saw him without that quiet smile. He must be still smiling in God's lap.

His demise has left a huge space vacant in out heart. We all pry to Almighty for his family members. My GOD help them to recover from this unrecoverable loss. May I pray his soul be rest in peace forever.

I  an deeply shocked by this sad news. As president of IIT Kanpur Alumni Association and CFO of IIT kanpur Foundation, I had the privilege of working closely with Prof. Sanjeev Aggarwal, when he was DRPG, and then on IITK Vision 2020. Sanjeev's affable nature and his quiet efficiency and dedication to IITK impressed me. He was able to get people to work together and bridge differences effectively. His good nature and wonderful sense of humor will always be remembered. He made invaluable contributions to IITK. We will all miss him dearly. With deepest sympathies to family and friends, Abhay Bhushan, IITK BTEE 1965 (First Batch)

May his soul rest in peace.

Shocked to hear demise of Prof. SKA. One of the great people I've seen. A great loss. May his soul Rest in Peace.

I'm very disturbed after hearing this news. He was like a father figure to me. Working under him and Mainak Sir had a profound impact on me and changed my life forever. We have lost a great Prof, guide, HOD, Dean, Director and above all a great human being . I pray to god to give his family, friends and the students working under him the strength to overcome this major loss. RIP SKA sir. Santhosh Sharma M.Tech. CSE IITK Batch of 2009 07899046299 (SKA Sir was my M.Tech. thesis guide)

Very sad to hear the news of Sir's demise..He was one with a calm demeanor and was very easily approachable..Rest in peace Sir. May God give your family the strength to overcome your loss.

Prof. Aggarwal was my ESC204 tutor in the early 90s. I am shocked to learn of his sudden demise. I pray that peace be bestowed on his soul and may his family have the strength to move on.

The sad news of the demise of Prof Sanjeev Aggarwal was shocking and unbelievable. Though I had very limited set of interactions with him (since I had met him for the first time in 1986 at TRDDC, Pune), these interactions were very pleasant. I am still not able to believe the news. May Almighty give a lot of strength to his family and friends to cope with and move forward in life. I know this is not easy.

Really very sad & shocking news ! He was a great scientist and my good neighbor & friend. Its great loss to IITK. May God bless him peace in heaven and strength to family to bear this unbearable loss.

Deeply shocked by the news, one of the great professor who keep the interest alive throughout the course. His way of teaching and knowledge was incredible. RIP sir.

Sanjeev sir was a kind hearted, generous man who will leave a big empty space in our lives.

Shocked to hear this. Dr. Aggarwal was a great mentor. He was always available to help out and share his experience whenever I reached him for guidance. He has been a great source of learning. I would definitely miss him.

I am deeply saddened to know about the sudden demise of Prof. Aggarwal. His compiler design course was the best course I took at IITK, and that was perhaps the only course that made me really think like a Computer "Engineer".

I did the compiler course offered Prof. Agrawal and it was one of the courses that I actually enjoyed. I was strongly influenced by the clarity of thought and speech in his lectures. He was very helpful and considerate in dealing with students, I got reprimanded a few times for not being on time to the lectures and for sloppy project work, but he never turned down any reasonable request that I had to make of him. Professor Agrawal will live on in my memories as an excellent teacher and an admirable and imitable human being.

I am stunned by the news. He was a great professor. Rest in peace prof. ska.

Prof. Sanjeev Aggarwal was a true guide and mentor and a great human being. I couldn't have had a better boss than him to give a start at IITK. I will always remember the lessons of life he taught me.Losing a father figure like him is an irreparable loss.He shall always remain alive in our hearts. May his soul rest in peace and God give strength to his family to bear this loss. Will always miss you Sir.

I took two classes with Dr Aggarwal at IITK, and then interacted with him as a colleague once I became a Professor myself. He was always calm, helpful, and in good spirits. It is sad that he passed away when he still had so much to offer as an academic and an administrator. A huge loss to the broader Indian academic community, not just IIT K and BITS Goa.

Sir was my thesis advisor. He was friendly and supportive. A good professor and a great person. Rest in piece Ska :(

Rest in peace SKA Sir! We would always remember your course of compilers and one of the best course project we could ever have had at campus.

Shocked to hear about the demise of sir. I had known sir over CS101 tutorship and also during the compilers course which he had taken for our batch. His lectures were always clear and sharp for understanding concepts. I am really thankful to sir for his teaching and also sad about this news. May his soul rest in peace.

He was like my father. The stay of 5 years that I had at IIT Kanpur would not have been possible without him and Anuty. He had an outstanding skill of managing the trickiest of the problems with ease without any signs on his face. He was a wonderful cook and I bet, the ones who were fortunate to have a chance of trying his recipes would agree. He was and always be a mentor and a role model to me. He would always be alive in our hearts May his soul rest in Peace.

Prof. Sanjeev was my professor and advisor at IITK. He was very supportive through out my studies and helped me achieve my dream of pursuing a PhD. His experience and advices were invaluable. We cannot substitute his loss. Thank you for everything Prof. SKA.

He was exceptional teacher. Taught me a cource on Java/Computing in my second sem .. Jan 2006

I worked closely with Sanjeev while sharing a little load of the first year Computing course during my visiting tenure in 2005-06 academic year. Every discussion was always concluded with his traditional quiet smile. Too hard to believe !!! I pray to the Almighty to rest his soul in peace and grant strength to the bereaved family -- parents, Vinita, Anupama and Keshav.

It is a shocking news. Rest in peace sir. We will always remember the compilers course.

Professor Sanjeev Aggarwal was one the best teachers I have had the opportunity of taking a class with. His compilers course was really legendary. Prof Aggarwal was also one of the most approachable professors in the department and I clearly remember seeking career advice from him, close to graduation. His sad demise is a great loss for all of us. May his soul rest in peace.

He was one of the finest person I've ever known. The first day I attended his class(Advanced Compiler Optimization) on July 2010, I was overwhelmed to see the way he presented the concepts in the most lucid manner. I considered him as an idol and got one of the biggest shock on Jan 11 to learn about the mishap; I could hardly get sleep. It's not only difficult but also excruciating to acknowledge the fact that professor is no more.

This is indeed a very big loss to us. We have lost a outstanding personality and great mentor. Lets pray the Almighty to give strength to the family to withstand this unbearable loss. No words can explain the pain and sad of this moment.

This is unbelievable. I am deeply shocked to hear this sad news. Prof. Aggarwal was a well disciplined and wonderful person. I very closely worked with him for three years when he was DRPG. He will be remembered as a person of high dedication, calculated and very efficient in working, good nature and for his very co-operative and supportive attitude. I pray GOD to give strength to his family to recover from this irreparable loss. May I pray his soul be rest in peace forever. Mohammad Shakeel DR(R&D) IIT Kanpur

Very very sad to know indeed. I belong to the list of countless people who had sought his help and came out with a lighter heart. Rest in peace Sanjeev Sir, you will be sorely missed.

Ska sir was my MTech thesis guide and it was under his guidance that I understood the meaning of research. Apart from that he was a great cook and host. Will always remember the stories he told about a student who had a horse on campus and another PhD student who was on campus for 10 years :) Wishing that his family are able to sail through these troubled times and may his soul rest in peace.

He was just a great teacher and learnt a lot from him. I still remember hall day and some of the conversations we had, those moments would be preserved in my heart. May his soul rest in peace.

I am saddened to hear this. Dr. Aggarwal was an inspiration to us. I remember him as kind and honest. May God bless his memory. May God give strength and consolation to his family.

I am shocked to hear this news. Such a good man! What a loss! I sat with Prof. Sanjeev Agarwal recently in June in a thesis defence in CSE.

I pray to god to give strength to his family members. He was very generous person.

Its a shock to know that Ska sir is no more with us. I had attended Advance Compiler course taken by him. He was a wonderful lecturer and more a motivator to me. This is a very big loss to CSE department, IITk and field of computer science.

This is a socking sad news. Myself and my son(Ashish yadav) is associated with all members of Prof. Agarwal's family.We pray to god for peace of his soul and bear his family for sudden death.

There is no other person who impressed more than SKA sir. He was best in everything he did. He was most influential teacher I had, Animation of slides which he created with his slide pointer in lectures of legendary course 738 are still printed in mind so clearly. In fact even before entering IITK, when I was preparing for GATE exam, I found a website which hosted great slides about Compiler course and only referred those slides for Compiler course. Later, when in IITK I realized the slides were from SKA sir. What a great administrator he was, I can always hear his strong and clear voice in my head. I never saw anyone so efficient at administrative work in my entire life. He was perfect guide one can wish for. During initial period of my thesis work, I was totally confused about so many articles and papers available for GPUs and graphics and was completely lost. I went to him and he said, forget graphics and everything, just think its a vector machine and what would do about to use it. Everything completely changed immediately. He always guided with such clarity and talking to him was always liberating. Best of all he was a great friend. He always use to call or personally meet whenever he knew some student was not well. All the stories he told about IITK made everyone laugh to the core. There are endless memories. He always be with us, in heart and mind. May his soul rest in peace.

I am shocked to learn the sad news. He had such an easy going and friendly manner - and always with a smile. Very sad that he left behind his family and friends at such a young age. My empathies for his family. His contributions to IITK will be long remembered by those of us who had the good fortune to interact with him. May his bereaved family find some consolation in the legacy he left behind

Prof. Sanjeev Kumar Aggarwal was the best teacher i have had in my life. In a single course on compilers we were able to observe his exceptional abilities of organization and competence over subject matter. His sudden demise is indeed very tragic. May his soul rest in peace.

It is hard to believe that you are gone so soon. We will miss you dearly. May your soul rest in peace. Our sincere condolences to Vineetha, Anupama, Keshav and the rest of the family. asish and aradhana.

Oh no!. Its a big loss to the teaching fraternity, specially CSE. He was always helping to the needy. GOD may bless him. Our sincere condolences to all his family member. Anil Yadav from C.S.J.M University, Kanpur

I am shocked and saddened at this unexpected news. I still remember the excellent compilers and advanced courses at IITK taught by SKA (and still use techniques I learnt there). My condolences to SKA's family and to his academic family.

We shall always miss a gentleman like you sir. Our condolences to Vineetaji & the family.

We have lost a great mentor and an advisor. This comes as a sudden shock and I am deeply sad from it. My heart felt condolences go with the family. Prof. Sanjeev advised me during my Mtech at IITK and also hosted my visits at IITK. :( . There are very few people in the world who touch so many lives of students and faculty.

Prof Agarwal was the DRPG when I joined IITK & i had a brief interaction with him then and a heartfelt smiley nod association thereafter. He was such a sharp man that his explanation on mobile phone technology to a non-tech person like me was so clear that it was a quantum leap in my understanding and i have quoted it thereof so many times thereof. But there are a lot of smart people around, the real magic was in his character, his warmth and simplicity - a true intellectual indeed. Farewell, my friend.

Sanjeev was full of life and ever enthusiastic and intense. I can't believe that he is no more. Back in the mid-eighties, we were neighbors in the C block of Hall 5. He had an enormous sense of propriety and was ever willing to help others. May the Almighty give his family and aged parents the strength to bear this irreparable loss!

A great leader and wonderful human being I got a chance to work with though too short a time at Bits Pilani goa campus. However a lot to learn from you. Will miss u prof Aggarwal.

Sanjeev was the head of the department when I joined as a faculty member. Without his kind help, it would have been much more difficult for me to get settled in the campus during the first several months. Later I collaborated with Sanjeev in developing a course on program optimization and together we attended several workshops and conferences organized by Intel. Sanjeev played a key role in connecting me with several researchers in Intel, a collaboration that I have immensely benefited from. Three things about Sanjeev prominently stand out in my memory: his eagerness to help, his systematic and organized mind, and his dedication toward whatever he does. In everything that he put his hands on, he would take care of every minute detail meticulously. I still find it hard to believe that I won't be able to talk to him again. May his soul rest in peace.

Sir, you are a legend and your work and your personality will never fade in the history of technology and teaching. We all engineers salute you. May your soul rest in peace or you should be given the job of teaching in heaven too.

I was working under his guidance for my PhD thesis since 2012. He very was so approachable, and for any small problem also, he comes down to student level to help. After every meeting with him I used to feel so encouraged, happy and used feel that my burden is reduced. For each step, he used to help me in going proper direction. And suddenly it is very sad to hear that he is no more. I pray god to rest his soul in peace.

Prof Sanjeev Aggarwal was very kind towards his students. I took Compilers course offered by him. He was one of few teachers in iitk who knew my name. I pray to almighty that his family gets peace and strength in this tough time. He will be living with his students.

I remember Dr. Aggarwal not only from IITK, but also recently when he visited IITK alumni here in Hillsboro, USA as DRPG. I think he did exemplary service to IITK, reminding us in his kind and gentle way about our duty to give back to our alma mater. My heart-felt condolences to his entire family, may God give you the strength to bear this loss. He will live long in the hearts of all the students he touched throughout his life...

This is very sad. He was one of the best teachers at IITK. I remember his compilers class. This was our 2nd or 3rd year, and I was struck by something that he used to do routinely in his class, but I hadn't seen anyone else do in their classes until then. It was an act as simple as this: he would try to sense if his audience was confused during a lecture, and if so, he would just stop. He'd stop and not move on until he had attempted his best to clarify. A lesser teacher would have easily moved on, but he didn't. He deeply cared about his teaching and our learning. His class project was one of the most "real" coding projects we did in our 4 years. I thank him for the difference he made for us.

It was shocking to hear that. I first met him, when he was doing is PhD at IIT/K and was working with a girl of our batch who had opted to work in computer center for short time(He used to work with VM Mehrotra, who was also a TA or had just become a prof at that time). Then I heard of him in TRDDC, where he was working on CHILL compiler and was one of the key guys for Keshav Nori. Met him in 2010, he was lively at that time too. Learnt later that he was working with Vivek Sarkar at Rice Univ for the next generation of parallel compilers for future multi core CPU's(1000 plus cores). May God give strength to his family for this untimely loss.

I met him when I was Lecturer at UIET,CSJM University kanpur.May his soul rest in peace and God give strength to his family to bear this loss. Ashutosh Kumar Singh,Asstt Professor,IIIT Allahabad.

This is so sad. My prayers with Professor Aggarwal's family. "SKA" was one of the most helpful CS faculty member I met during my BTech tenure. His office door was always open to us (literally too). SKA took our compilers course. He was a fabulous instructor with patience unparalleled. Topics like compilers are never easy to grasp but he made it navigable for us. It is a great loss for all of the IITK diaspora.

Prof. Aggarwal's course on compilers was indeed legendary. We (Btech CSE class of 2002) learned so much from him. I also took advanced and independent study courses with him. It is quite devastating to know he is no longer with us. I can vividly imagine his calm smiling face. My heart goes out to his family and friends in this difficult time.

My heartfelt condolence on the sad and untimely demise of Prof. S.K. Agrawal. I pray to God , give peace to the departed soul and strength to the grief stricken family to bear irreparable loss. Dr. Dheerendra Singh @BITS-PILANI

Extremely shocked to hear this news. He was the first professor to introduce me and my batch to computer science. He was always very methodical in his teaching and it was a pleasure to learn from him. I am sure the department, ex and current students will dearly miss him. Hope his legacy as a professor and head of department continues in future.

His departure is a great loss to the academic world and I lost a memorable and a good friend of mine. It is shocking, saddening and disheartening to see such wonderful people depart at such an early stage. He is a wonderful human being. My hearty condolences. C.Pandu Rangan, dept of CSE, Professor, IIT, Madras.

I happened to take a course under him, during my first year as a bachelor's student at the institute. He was a very kind, calm and helping person and at the same time expected all the students to push beyond the limit. He was a great teacher. I had no clue or any background in the course but he was able to make it enjoyable and tangible. A lot of my friends had worked closely with him and I always heard about his helping nature, energetic demeanor and positive outlook. He was greatly loved and respected. He will be missed by the institute and its people. Rest in peace Sir. I am sure your presence will live on

When I first met Sanjeev I found him affable. During the course of our interaction I got to see his personal side: a truly genuine and helpful individual. I was looking forward to an extended interaction. Unfortunately, this is not to be.

Shocked to learn about sad demise of Prof. SKA. He is an inspirational person to many student's like me. My heartfelt condolences to his family.

It is deeply saddening to hear the unexpected demise of dear Prof. SKA. In spite of 20 years having elapsed since I completed my thesis under him, Prof. Aggarwal took the time to always stay in touch. Prof. Aggarwal had a way of connecting with people that was very unique-- even my kids loved to interact with him whenever he visited our home. He will always occupy a special place in my heart for his mentorship when I needed it the most. My sincere condolences to his family that he leaves behind and may his soul rest in peace.

I think the world will fondly remember him as just ska. Was shocked to hear about his passing away so suddenly. I recall he used to teach Esc 101 with a hint of humour.

Dr. SKA was an amazing teacher with a lot of patience. He was so much student friendly. I will always remember the way you taught us. As a human being, he was very kind and helpful. My heartfelt condolences are with his family.May his soul rest in peace.

I am extremely shocked to hear about this sad news. Prof. Aggarwal's legendary compilers course helped built up character and provided me skills that I continue to use extensively to date and pass on to other students. His affable personality was always something to depend on and remained as one of my defining impressions of IITK. We had met several times and kept in close touch through email since I graduated from IITK in 2000. I still very vividly remember my interactions with him when I last met him in 2012 at IITK where ISEC was being held and Prof. Aggarwal was its general chair. There are very few people like him with such a balance of academic and administrative interests and accomplishments. It is a terrible loss for the burgeoning Indian academic environment that had so much to benefit from Prof. Aggarwal's efforts. Where ever he is, he will continue to be a source of great inspiration for the lives he touched. My heart goes out to his family - May God give them the strength to navigate through this untimely loss and move forward in life with his inspiring memories that will never fade away.

It's my privilege to meet a person like him in my life. In just 5 months he brought a tremendous change in our campus in all the ways. He is an exceptional person that GOD gave me the chance to work along with him . The inspiration, given by him at the institution level , the dept. level even at the individual level in this 5 months will be there with us for our life time. Ma'm ,Keshav and Anupama I pray GOD, to give you the courage to go on in your life with all his precious memories.

Sanjeev taught me Compilers during B.Tech., and taught me how to teach Compilers when I joined as faculty at IIT Kanpur. For last 3.5 years, he had been been constantly helping me in my professional activities - courses, projects. I could just walk into his office any time for guidance on any matter. I worked with him for organizing few conferences, and was amazed by his organizational skills and management. He left a void in the IITK-CSE dept when he left for Goa, but the void that he has left in our heart now can never be filled. We will miss him forever.

The news of Prof. Sanjeev's Death is extemely shocking to me & my wife personally. He was very kind , helpful & inspiring to our son harshit who studied with his son Keshav right from Kishlaya. I shall never forget how he encouraged Harshit during his first semester of B.tech at NITK Surathkal for excelling his performance. He himself used to ask us for sending any thing for Harshit whenever he had his visit to NITK. We shall miss Prof. Sanjeev forever. May God rest his soul in Peace & give enough Strength to his old parents, Vineeta Ji & Anupama to bear this shock of the lifetime. OPM

I am deeply saddened to hear of Prof. Aggarwal's untimely demise. I still remember the advanced compilers class he taught in Fall 1990. That class inspired me to take up compilers and static analysis as my research area, and 23 years later, I still consider myself very fortunate to have taken that class from Prof. Aggarwal. Rest in peace, Sir.

I am very saddened to hear of Prof. Aggarwal's demise. I had the privilege to meet him regulary when I was visiting Faculty at the CSE dept of IIT Kanpur in the winter 2011-2012. I do remember his warm welcome when arriving at IITK and his kindness. I will keep the memory of a very warm person. My heartfelt condolences to his family and friends. Philippe Dugerdil, Geneva School of Business Administration

I am shocked and deeply mourned. He was my guide. He was the one who taught me how to do research. His affable nature has helped me interacting at ease. He will always be my mentor, his words will always be remembered and will guide me in future. We had exchanged mails only a week ago for submitting a paper in a conference. I could not believe he is no more. May his soul rest in peace. May god give strength to his family.

SKA sir was an exceptional teacher and a very warm human being. Since, it has been quite a few years, I have forgotten most of what I learnt in the course on Compilers. However, what I have not forgotten is the enormous warmth he exuded and of course, the ever-present smile on his face. May he rest in peace.

I knew Sanjeev well for many years now having co-chaired ISEC with him a few years ago. This is indeed a great loss to the entire extended computer science family in India.

The news came as complete shock and hard to believe. I was looking forward to meeting ska sir during the Security & Privacy Symposium at IITK. The loss is unbearable. He was my M.Tech thesis supervisor and I'd taken his Advanced Compiler Optimizations which was simply the best course. He used to explain any topic in such simple manner using illustrations that even complex concepts will become clear to students. I have learnt so many things from him - right from how to read papers critically to how to deal with problem in systematic way. His inspiring, always calm and patient personality, his words of encouragement will always be remembered and he will always remain in our hearts. May God give strength to his family to bear the loss.

This is still hard to believe that Sir is not with us. I was fortunate to have Sir as my thesis supervisor and I have learned so much from him. How can I forget his passion for everything. Science, technology, teaching, discussions, brainstorming sessions. He was an exceptional teacher and a great mentor. May god give enough strength to his family to bear this shock. Rest in peace Sir! You will always be missed!

I am shocked to hear about this loss. When I visited IIT Kanpur during Fall of 2002, Sanjeev made me and my family feel at home at the campus. It was always a pleasure to interact with him. He made immense contributions to IIT Kanpur computer science department. My heart-felt condolences to the family. Vijay Garg The University of Texas at Austin.

I am so sorry to see passing of Dr. Agarwal. He was a great mentor and a good teacher and will always fondly remember taking classes from him in my IITK days. My condolences for his family.

Very sad and unhappy. I started working with him for the last two years and had plans to continue. We have very few people working in compilers and program analysis. Its very unfortunate.

Very very sad and hurt about his sudden demise. May his soul rest in peace.May god give comfort to his family and provide them a good future. His contribution to the field of computer science research and the department is very extreme and especially in the area of software engineering. I had done courses under him and he is my thesis examiner. I learnt many things from him, he gave me a lot of feedback and suggestions for improving my technical background. Hope i will use it in my future and bring a good name to him.

Sanjeev was a close friend and a highly valued professional. A very calm person he brought new insights into everything he handled as a professor and as a dean. His very untimely departure has deeply saddened his family and untold number of former students , friends and colleagues. We wish his soul eternal peace and enough strength to family.

I am shocked to hear this news. He was a great teacher and an administrator. I consider myself fortunate to have interacted with him during my PhD program and later. I always found him motivating and encouraging. Its a great loss to nation.

Professor Aggarwal was the instructor in the very first lecture I attended at IIT Kanpur, almost a decade ago. Yet, his charismatic teaching was such that his impromptu demonstration of how pervasive computers have become still remains fresh in the mind. He was the first mentor I had at IIT Kanpur, and I will always remain grateful to him for all the advice, encouragement and last but not least, his extremely enjoyable and highly instructive classes.

I cannot forget how he encouraged me and my partner Lokesh, to work around an idea which is finally going to become a company in a few months! I will NEVER forget what he told us in that office his, EVER. We are forever grateful for it. May his soul rest in peace.

I remember Sanjeev as extremely warm hearted and generous to a fault. His vibrant and endearing persona will be sorely missed. At meetings when the going would become slightly dreary he often brought smiles on the faces of people with his sense of wit. His technical expertise on Compilers and Language Processing was unmatched in more ways than one. I attended some of his lectures way back in 1998. He taught and communicated with aplomb and authority. Whether they be students in his class lectures or audience in a seminar/ workshop, they always came away impressed and satisfied. His untimely departure, while in the prime of his professional career and the suddenness of it all bleeds my heart.

Really sad to hear of passing away of prof. Sanjeev. We had worked closely for software engineering conferences including isec, and the comfort he had with numbers was amazing and he was the default choice for finance chair for many conferences including the prestigious icse in hyderabad 2014. Had the previlege of meeting him in person in goa two months back and he seemed to really enjoy his tenure at bits goa. May his soul rest in peace and god give his family strength to cope.

I was really shocked to hear the news. Sanjeev was a very good freind while I was in IIT/K and later. Indeed, no visit to IIT/K was complete without dropping into his office or home for a quick cup of tea. I and my wife, Aditi, will really miss Sanjeev, his good humour, pleasant company and, of course the results of his culinary experiments. Our sincere condolences to Vineeta and his family. May God give them the courage to bear this severe loss.

Deeply shocked to hear about the sudden demise of Prof Aggarwal. Pray that God gives strength to all at this time of grief. He was Head of the Computer Centre when I was studying there, and I have interacted with him several times. Truly someone to look up to. <a href="http://www.youtube.com/watch?v=nI51ESCus1U">Zindagi Ka Safar Hai Yeh Kaisa Safar</a>

For last two decades, I had developed a strong bond of relationship with Sanjeev and his family (beause both his daughter and son were not only the students of my wife in the Kislay Nursery School,but they were learning vocal music from her too). Even I had the opportunity to work with him in different capacities at the Institute, to start with as a Warden of Hall V in early 1990s and subsequently in SPGC and lastly Sanjeev as DRPG. Through all these professional associations I have found in him a good human being with a charming personality, who was always in smiles. He was always committed for the cause of the student and staff. Both myself and my wife deeply mourn the untimely death of Sanjeev. We pray Lord Almight to give courage and strength to Vineeta,Anupama & Keshav to bear this great loss.

Really very sad & shocking news ! He was a nice person . Its great loss to IITK. May God bless him peace in heaven and strength to his family to bear this unbearable loss.

It was shocking to hear that. I first met him, when he was doing is PhD at IIT/K and was working with a girl of our batch who had opted to work in computer center for short time(He used to work with VM Mehrotra, who was also a TA or had just become a prof at that time).

Prof. Sanjeev Aggarwal was one of the best teachers I met in my life. A nice mentor with strong personality. I am Shocked to hear this news. May his soul rest in peace and God give strength to his family.

Prof Aggarwal, we will miss you. I will always treasure you as a fine colleague and working with you closely during KIAP IITKanpur Golden Jubilee event. Hope that your family will have the fortitude to bear this irreparable loss. RIP.

Very sorry to learn this. Knew Sanjeev quite well during my Kanpur days. My sincere condolence for his family.

Myself alum of 2011 batch worked very closely with him for more then 2yrs in DRPG in Alumni Contact Program. Today whatever I have learned as how to handle management and real life problems is because of Sanjeev Sir. This year I was very angry with myself as this was the first time in last 6 years when I forgot to wish him Teacher's Day and had promised myself that in 2014 I will personally greet him bt God has taken that last chance from me. Really shocking news. Deep condolense.

I am sorry to hear about his sudden demise. He was an exceptional teacher and a good human being at heart, I know for sure as I had taken a course with him and spent considerable time with his exceptionally good classes. May his soul rest in peace. Sir, we will always remember you in our heart!

It is great to see so many wonderful comments. Like most he taught me compilers but we also had conversations at the dinner and coffee table. I wish I could speak more with you. :(

A nice mentor with strong personality. I am shocked to hear this. May his soul rest in peace and GOD give strength to his family.

Heartfelt Condolences to family and friends. We are all in shock at this terrible loss to all of us at IIT K community.

It is indeed very shocking to realize that Prof. Sanjeev Kumar Aggarwal is no more with us. It is difficult to overcome this shock even after a week. He was a person full of ONLY positive energy. I have the memories of countless occasions when I saw his noble qualities. On professional front, he was an excellent researcher and an outstanding teacher. His organizational skills were so good that everyone in the department got benefited and inspired by this quality. He used to feel happy on every occasion of success of any faculty member or student in the department. He used to help every one who approached him. I wish I could have such a sensitive and large heart for others. As a person, I found him extremely balanced person having peace all the times. As a colleague, he was like an elder brother to me. He truly practiced the philosophy that one should see only positive qualities in others instead of wasting time and peace in criticizing others for their mistakes or bad qualities. I got benefited by his wise advices on many occasions. It is indeed hard to believe that he is no more with us. I sometimes doubt even the Nature/God for taking away a person who could give some much to the society. I am sure he will be remembered by me, students and colleagues for his great qualities. May God grant eternal peace to him.

May his soul rest in peace

keshav, its very sad to know about the sudden demise of uncle. i was informed 3 days back by shad. i cant gather the courage to call you. may his soul rest in peace.

It is quite shocking to hear this news. Dr Sanjeev Kumar Aggarwal guided me for my M.Tech, including my thesis dissertation, during 1999-2001 in CSE department at IIT Kanpur. If my Post Graduation days were memorable to me for anything, it was primarily because of my association with him. I cherished the wonderful discussions we had. I treat him as my real Guru. He is more than just a teacher for me. I always remember him for the inspiration I have drawn from him. My deepest condolences to his family.

We pray to almighty for giving peace to the departed soul and give courage to the family to bear the loss. He was so young to leave

It was shocking to hear that. I first met him, when he was doing is PhD at IIT/K and was working with a girl of our batch who had opted to work in computer center for short time(He used to work with VM Mehrotra, who was also a TA or had just become a prof at that time). Then I heard of him in TRDDC, where he was working on CHILL compiler and was one of the key guys for Keshav Nori. Met him in 2010, he was lively at that time too. Learnt later that he was working with Vivek Sarkar at Rice Univ for the next generation of parallel compilers for future multi core CPU's(1000 plus cores). May God give strength to his family for this untimely loss.

Shocked to hear this. May his soul rest in peace 

Prof. Agarwal was disciplined person. I got oppurtunity to work with him when we went to Jabalpur as Institute representatives for conducting JEE Exam. His strictness towards duty showed his style of working.

RIP Sir

I had the privilege of working closely with Prof. Sanjeev Aggarwal@ Bits Goa, Great Administrator and a great humanbeing. He was like a father figure to me.We all miss u Sir!

God let his soul rest in peace. H.C.T IISER Bhoapl

I had gone to visit the Physics Dept. of BITS Pilani, Goa Campus for 5 days on Nov. 20, 2013. When I reached around 3 Pm their Guest House, I was told that their Director did not want them to take me to his office. Instead at around 7 Pm, I got a call that he is already in the lounge of the GH. As I was going out, the bell rang & Sanjeev came in. I was elated to see him after nearly 8 years since I left IITK. We talked for nearly an hour. He seemed to be enjoying his work. I found later that faculty members there were extremely happy since he was bringing IITK culture, namely openness & no hierarchy. I was informed the very next day after his demise the terrible news which gave me a shock. I wish I had not visited Goa. My heartfelt condolence to the whole family.

I have learnt many things from Sir. He has been continuous inspiration to me. We grieve and mourn this huge loss to his family, the department and IITK.

It was really very shocking to know the demise of prof. Aggarwal,he was always so kind to me whenever i meet him....it has been long time when i saw him last, we have lost a wonderful man..I will pray god to give power to his family...May his soul Rest In Peace.

A tearful news for me. I recently met him at IIT Bombay in 2010 summer. I used to have panja (a kind of fist fight over table) in Hall-5 at IITK during our PhD days. I used to go with Sanjeev & Harish Karnick for ice cream after our dinner at the mess many a times. I lost a nice guy & good friend. We had a great time in Hall-5 during late 1980s. I pray to Almighty to give great strength to Vineetaji, Anupama & Keshav. Still it is unbelievable !! A shocking news !!

I can not believable this news. I am shocked beyond belief to think that Sanjeev is no more. I had been fortunate to be friends with Sanjeev for several years as floor mates in Hall 5 and I always remember our days fondly. We kept in touch occasionally through the years via email. Sanjeev was simply a great guy and was snatched from us far too early. We are robbed of many more great achievements that were forthcoming from him. RIP Sanjeev.

God give a solace for his soul...He'll be always with us as a memorable person..

Professor Sanjeev Aggarwal will be sorely missed by innumerable people in innumerable ways. A fantastic teacher, one who taught Compiler design to generations of students, will be missed. A renowned researcher and scientist, one who contributed to Compilers research during its early days in the nation, will be missed. But most importantly, a gentle adviser, a fierce friend and a fantastic human being, whose smile was infectious to even the most depressed soul, will be missed above all - Rest in Peace, "Ska" Sir.

I am shocked and deeply saddened by Prof. Aggarwal's passing. I have fond memories of his course on compilers, and especially of his gentle and kind nature even while setting high standards. The course was easily the most humbling, yet gratifying experience in the computer science program. My heartfelt condolences to his family and the IITK community. Sincerely, Ashwin

I am sorry to hear about Prof. Aggarwal's passing away. I enjoyed his course and he also my BTP advisor. The start I got working on compilers then stays with me. My condolences to his family and everyone around him who feel his absence the most -- wishing them strength to cope with this untimely loss.

Prof. Sanjeev kumar is very a jovial person with ever helping nature, lot of common sense and practical knowledge in many fields. It is great a loss for the Compilers group, for the CSE dept and the family. My condolences for the young Keshav and Anupama and the elderly parents of Sanjeev( and no words for Vineetaji). I am sure Prof. Sanjeev kumar will be in the hearts of all of us for ever.

He was one of the best CSE teachers at IITK. An amazing teacher teaching compilers as a wonderful combination of theoretical and applied computer science but more importantly, he was a gem of a person. He was very patient and easy going with the students but still managed to push them to excel. He will be missed. Sincere condolences to his family.

It is very shocking news!!!!! Unbelievable. How it happened>

It's now more than a month since that terrible afternoon, and yet, the grief and the sense of loss is no less. It's difficult to describe what Sanjeev was to our Department-- collectively we had the confidence that whatever be the demand or need, we could depend on Sanjeev. Sanjeev's commitment to the Department was absolute-- he left for Goa only after ensuring that the area of compilers and language processing would be well looked after in his absence. He was a natural leader-- in all kinds of situations, especially the ones which were difficult ones, one would discover after a while that Sanjeev was in the lead. Everything that he did, he did with great grace. And he was a great friend. We'll always miss you, Sanjeev.

sir i am not lucky to attend your lecture but may god give peace to his soul

I am very shocked with this sad demise note at IIT-K web site :( . This is loss to IIT's, computer society and research community. I know Sanjeev sir since I was in my 3rd year Btech (2009-10) through internet and NPTEL. His online notes are very worthful to the studies. During NPTEL workshop at IIITDM-Jabalpur I met him first time and asked a question for which he gave me excellent answer, and in lunchtime sir teach my friend and me how to find research problem for thesis work. RIP Sanjeev sir

Professor Sanjeev Agarwal was an excellent teacher with deep knowledge in whatever he teaches, had immense patience yet composed and down to earth person. My MTech days spent under his mentorship will be cherished for all his life. He will be missed by many hearts. My deepest condolences for his family. Sarath Kumar

This is such a shock to hear about Sir's untimely demise. Immediately the mind races back to the time when sir taught us compilers. Much beyond the excellent teacher he was, the thing which distinguished him was that he had special sensitivity for and took special care of the students like me who were lagging in the subject. I will always remember sir as a great mentor and father figure. My condolences.

I have had the opportunity to interact briefly with Prof. Sanjeev Aggarwal at various conferences. He was an excellent organizer, and very warm and friendly even with new acquaintances. He was a prototypical academic. We are all going to miss him heavily.

May his soul rest in peace !

Dr Sanjeev Kumar will always be remembered for his kind attitude and polite nature. During his headship, I closely worked with him and found him as a gentleman with guts of such position. May God rest his soul in peace Nadeem Ex Project Staff @CSE Lab 737 9227 737

I am very sad to know the demise of such a nice person at such an young age. I was at the Institute only for a few months. He was one of the nicest persons.
