#### 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 students’ accomplishments from the REU Summer 2019 Program. Due to the uncertainties surrounding the coronavirus disease, the REU Summer 2020 Program has been postponed to 2021.

### General Information

I received my 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 then joined the faculty at The University of Tennessee at Chattanooga in 2012. I was privileged to have learnt, also, from Professor Daniel A. Goldston at San José State University.

### Research Interests

My work lies in the fields of number theory and probability. It concerns the Riemann zeta-function, Dirichlet’s L-functions, the distribution of prime numbers, random polynomials and random series.

This is a link to my curriculum vitae.

This is a list my publications.
