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

We gratefully acknowledge grant support from the National Science Foundation. This NSF REU grant enables us to organize a Mathematics REU Site in Chattanooga. We have recruited ten talented undergraduates for our Summer 2019 REU Program.


Graduate Studies in Mathematics

The Graduate School Applications for Spring 2020 and Summer 2020 are now live. Click on the links below for our mathematics program applications:

Please contact me if you would like to learn more about the application process, admission requirements, assistantships, course offerings, research areas, and internship opportunities.


General Information

From Drummondville, Québec, to San José, California, to Urbana, Illinois, to Rochester, New York, to Boston, Massachusetts, to Chattanooga, Tennessee—I suppose this makes me someone with great wanderlust and a keen interest in exploration. J’ai une imagination débordante—tu le sais bien. Before drifting into mathematics, I spent many moons at Orion Instruments Incorporated and Trimble Navigation Limited designing in-circuit emulators and GPS firmware for navigation, tracking, data collection, and timing—Memories! 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 worked on prime numbers with Daniel Goldston at San José State University. I joined the faculty of University of Tennessee at Chattanooga in 2011 and currently work as Associate Professor of Mathematics.
