Research Interests

My research interests are in Representation theory (particularly, in Cherednik algebras, quantum affine and toroidal algebras, shuffle algebras, and shifted Yangians) and its connection to Algebraic geometry (via Laumon spaces, Nakajima quiver varieties, and quantum cohomology)

Mentoring at MIT PRIMES program

I had mentored Fengning Ding during 2011‒2013 in the MIT PRIMES program. With our project, Fengning won the 4th Prize at 2012 Intel STS US national competition (\$40,000 award) and became 2012 Davidson Fellow Laureate (\$50,000 award).

MIT PRIMES is a free, year-long after-school research program for high school students from the Boston area. Program participants work with MIT researchers on exciting unsolved problems in mathematics, computer science, and computational biology.
