Associate Professor; Ph.D., Purdue University, West Lafayette, 2012. Number Theory, Automorphic Forms and Representation Theory

Research Interests: 

My research interest lies in the fields of number theory, automorphic forms, representation theory, and harmonic analysis on reductive p-adic groups. I am particularly interested in questions arising from the Langlands program.
