General Information

From Drummondville, Québec to San José, California to Urbana, Illinois to Rochester, New York to Boston, Massachusetts and then 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. I received the Ph.D. in Mathematics from the University of Illinois at Urbana-Champaign in 2007 under the direction of Professor Alexandru Zaharescu and worked as a postdoctoral faculty at the University of Rochester and conducted research under the guidance of Professor Steven M. Gonek from 2007 to 2010. I have also served on the faculties of Boston College and The University of Tennessee at Chattanooga, where I am currently an associate professor of mathematics. Before drifting into mathematics, I was with Trimble Navigation Limited (Sunnyvale, California) and worked as a senior member of the technical staff designing in-vehicle navigation and time and frequency products. Memories!


Area of Research

My area of research is in number theory. My favorite topics are L-functions, prime numbers and Farey fractions. I am also hard at work on probability theory, most especially random polynomials. This year I am taking graduate students and am happy to talk with you about projects in these areas leading to a Master’s thesis with good prospects for a journal article. Undergraduate students are strongly encouraged to work on a departmental honors thesis and to obtain hands-on research experience during the summers by doing an internship at a national laboratory or participating in a Research Experiences for Undergraduates (REU) program which will allow you the relevant research experience before you apply to Ph.D. programs. The Ph.D. program is all about research.


Teaching Duties

I am dedicated to the goal of promoting significant learning experiences among my students. I love learning, teaching mathematics on various levels and helping students. This summer I will be teaching

  • MATH 1960 (Calculus with Analytic Geometry II)

In the fall term of 2016 I will be teaching

  • MATH 1960 (Calculus with Analytic Geometry II)

  • MATH 5560 (Real Analysis)
