  • 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.
