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
I have been organizing the following events:
Duke Opportunities in Math (DOmath)
Public Lectures Unveiling Math (PLUM)
Summer Workshop in Math (SWiM)
Ph.D. in Mathematics, 2004, University of Illinois at UrbanaChampaign, Advisor: Bruce C. Berndt
Algebraic Geometry Seminar
Number Theory Seminar
My primary interests are Automorphic Lfunctions, Relative Trace formula, Algebraic cycles on Shimura varieties and Representations of the classical groups,
but I am also quite fond of qseries, theta functions and partitions.
