General Information

After receiving the Ph.D. in Mathematics from University of Illinois at Urbana—Champaign under advisor Alexandru Zaharescu, I worked for University of Rochester for three years as a postdoctoral faculty under the supervision of Steven Gonek and spent the fourth year at Boston College as a visiting assistant professor. During this time I also worked on prime numbers with Daniel Goldston at San José State University. Before drifting into mathematics I worked for Trimble Navigation Limited and designed firmware for positioning, timing and navigation. Memories!

Area of Research

My research is 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 and arithmetic functions. I am also hard at work in probability theory and multivariate statistics, especially related 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, helping students and serving as faculty advisor for the Math Club. I am currently teaching:

MATH 2560 — Calculus with Analytic Geometry III
MATH 4280/5280 — Analytic Number Theory

I am excited to teach the following courses in the fall:

MATH 2450 — Introdution to Differential and Difference Equations
MATH 4250 — Modern Abstract Algebra I



I gratefully acknowledge grant support from the Mathematical Association of America’s Dolciani Mathematics Enrichment Grants Program and the Dolciani Halloran Foundation for my project Chattanooga Math Circle ($5,966, April 18, 2017—May 31, 2018).
