General Information

I received the Doctor of Philisophy (Ph.D.) in Mathematics from University of Illinois at Urbana—Champaign under advisor A. Zaharescu and worked as a postdoctoral faculty at University of Rochester under S.M. Gonek. During this time I also worked on the distribution of prime numbers with D.A. Goldston at San José State University and served on the faculty of Boston College. Before drifting into mathematics I worked at Trimble Navigation Limited and designed GPS firmware for positioning, timing and navigation. Memories!

Area of Research

My research is in number theory. I am particularly interested in the Riemann zeta function, L-functions, prime numbers, Farey fractions, arithmetic functions and sieve methods. I am also hard at work in probability theory, especially random polynomials and random processes.



I am dedicated to the goal of promoting significant learning experiences among my students. I love learning, teaching mathematics on various levels, and helping students. In Spring 2018 I will be teaching

MATH 2560 — Calculus with Analytic Geometry III
MATH 4280/5280 — Analytic Number Theory
MATH 4995 — Departmental Thesis

and serving as faculty advisor for the Math Club.



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).
