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. We are excited to have recruited eleven talented and energetic undergraduates for our 2019 Mathematics REU Summer Program. Our research groups are hard at work on interesting projects in pure and applied mathematics.

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 M. Gonek and for Boston College as a visiting assistant professor. During this time I also worked on prime numbers with Daniel A. 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.
