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.

Areas of Specialization

  • Number Theory
  • Probability Theory
  • Multivariate Statistics

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, random vectors, and stochastic processes that arise in approximation theory.


Teaching Duties

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

Fall 2018

  • MATH 2450 Introduction to Differential and Difference Equations
  • MATH 4250 Modern Abstract Algebra I

Spring 2019 (tentative)

  • MATH 4350 Mathematics of Finance
  • MATH 4600 Numerical Analysis I


Professional Service

I recently accepted an invitation to join the Editorial Board of Punjab University Journal of Mathematics (PUJM). I am honored to serve as an Associate Editor of PUJM. As such, I am happy to consider high quality papers in number theory, analysis, probability theory, and multivariate statistics for PUJM.
