General Information

After receiving the Ph.D. degree in 2007 from University of Illinois at Urbana–Champaign under advisor Alexandru Zaharescu, I worked for University of Rochester as a postdoctoral faculty under the supervision of Steven Gonek and for Boston College as a visiting assistant professor. During this time I also studied prime gaps with Daniel Goldston at San José State University. I joined the faculty of The University of Tennessee at Chattanooga in 2011 and currently work as Associate Professor of Mathematics. The photo above was taken in 2002 after I suspended my engineering career at Trimble Navigation Limited and moved to the corn fields of Illinois to study mathematics. Memories!

Areas of Research

My primary research interests are in number theory, mainly having to do with prime numbers and their connection with the Riemann zeta function. My other favorite topics are L-functions, Farey fractions, sequences, and arithmetic functions. I am also hard at work in probability theory and multivariate statistics, especially in relation to random polynomials and random processes.



I am dedicated to the goal of promoting significant learning experiences among students. I love learning, teaching mathematics on various levels, and helping students.
