REU Site: Research Training for Undergraduates in Mathematical Analysis with Applications in Allied Fields

This REU Site is supported by the National Science Foundation, and this support is gratefully acknowledged. This is a link to our REU studentsachievements from the REU Summer 2019 Program. Due to the uncertainties surrounding the COVID-19 pandemic, the REU Summer 2020 Program was postponed to 2021.


General Information

I received the Ph.D. from the University of Illinois at Urbana–Champaign in 2007, where I studied under the direction of Professor Alexandru Zaharescu. After completing my postdoctoral research under the supervision of Professor Steven M. Gonek at the University of Rochester in 2010, I taught at Boston College for one year and joined the faculty at The University of Tennessee at Chattanooga in 2011. I was privileged to have learnt, also, from Professsor Daniel A. Goldston at San José State University.


Research Interests

My work lies in the fields of number theory and probability. It concerns the zeta function, the distribution of prime numbers, equidistributed sequences, random polynomials and random summation.

This is a list of my publications.
