My current research interest is in the field of Knot Theory. Since Knot Theory is just about 100 years old, there are many open problems in this research area. In particular, I am interested in the study of amphicheirality, the study of closed braids, and the knot polynomials, specially the Jones polynomial.

शोध परिणाम
Solved Kirby's open problem on Knot Theory " Are there alternating amphicheiral knots of every even crossing number" with a positive, affirmative class of examples (JKTR Vol 16 2007).
Discovered new symmetries which give new classes of amphicheiral knots of braid index 3 (Proc Nat Acad Sciences,
Vol 81, 2011). Presently continuing research in the area of knot theory specially braid closures and Jones polynomials.
