Interview with Girls' Angle

My recent interview with Grils' Angle has been appeared in the issue June/July 2018, Vol.11, No.5.

My Quote

Be self-reliant. You don't need others' permission to pursue your goals.

Springer GTM Series

Together with Jayce R. Getz, I am writing a book for the Springer Graduate Texts in Mathematics (GTM series), expected to be published in 2019:
An Introduction to Automorphic Representations with a view toward Trace Formulae

Events at Duke

I have been organizing the following events:
Duke Opportunities in Math (DOmath)
Public Lectures Unveiling Math (PLUM)
Summer Workshop in Math (SWiM)

General Information

Ph.D. in Mathematics, 2004, University of Illinois at Urbana-Champaign, Advisor: Bruce C. Berndt


Algebraic Geometry Seminar
Number Theory Seminar

Research Interests

My primary interests are Automorphic L-functions, Relative Trace formula, Algebraic cycles on Shimura varieties and Representations of the classical groups,
but I am also quite fond of q-series, theta functions and partitions.
