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 incircuit 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.
Areas of Specialization
 Number Theory
 Probability and Stochastic Processes
Teaching Duties
I am dedicated to the goal of promoting significant learning experiences among students. I love learning, teaching mathematics on various levels, and helping students. In Fall 2019 I will be teaching
 MATH 2450 Introduction to Differential and Difference Equations
 MATH 4250 Modern Algebra I
Editorial Boards
I currently serve on the Editorial Board of Punjab University Journal of Mathematics as Associate Editor. I am happy to communicate high quality papers in Number Theory, Mathematical Analysis, Probability, and Multivariate Analysis.
