Welcome to my homepage!
I am a Gibbs Assistant Professor in the Department of Mathematics at Yale University.
I received my Ph.D. in Mathematics from University of California, Davis under the supervision of Misha Kapovich. Prior to that, I received my the Master of Mathematics degree in 2015 and the Bachelor of Mathematics (Hons.) degree in 2013 from Indian Statistical Institute, Bangalore, India.
Here is my cv.
Research
I am interested in discrete subgroups of Lie groups, geometric group theory, and non-positively curved geometry.
