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. I received the Ph.D. in mathematics from the University of Illinois at UrbanaChampaign in 2007 and have served on the faculties of the University of Rochester, Boston College, and The University of Tennessee at Chattanooga, where I am currently Associate Professor of Mathematics.
Area of Research
My area of research is in number theory. My favorite topics are Lfunctions, prime numbers, and Farey fractions. I also work in probability theory, most especially random polynomials.
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. I am currently teaching

MATH 1960 (Calculus with Analytic Geometry II)

MATH 4999/5910 (Mathematics of Finance)

MATH 4995 (Departmental Thesis)
In the fall term of 2016, I will be teaching

MATH 1960 (Calculus with Analytic Geometry II)

MATH 5560 (Real Analysis)
Research Experiences for Undergraduates
In 2013 the department received generous financial support from the National Science Foundation to organize and set up a Research Experiences for Undergraduates (REU) Site in Differential/Difference Equation Models and Number Theory for the academic years 20132015 (NSF Grant DMS1261308).
REU Summer 2013. Nine undergraduate students came to the REU Summer 2013 program to learn to do research in mathematics. Of these students, I mentored

Kathryn Crosby (Oral Roberts University)

Jordan Eliseo (University of North Carolina at Greensboro)

David Mazowiecki (William Paterson University)
and wrote a joint paper in analytic number theory. Kathryn is pursuing her Master’s in mathematics at Oklahoma State University, and Jordan works as a software engineer at International Business Machines Corporation.
REU Summer 2014. Of the nine undergraduate students who participated in the REU Summer 2014 program, I mentored

Katrina Ferrier (University of Tennessee at Chattanooga)

Micah Jackson (Georgia Southern University)

Dhir Patel (Rutgers University)

Huong Tran (Georgia Institute of Technology)
and coauthored a paper in probability theory. As a result, Dhir and Huong presented a 20 minute report talk at the Young Mathematicians Conference at The Ohio State University (August 2224, 2014). Katrina presented a 20 minute talk at Western Kentucky University's 34th Annual Mathematics Symposium, a research poster at the Emory UniversityLaney Graduate School STEM Research and Career Symposium (March 2527, 2015), and a research poster at the 7th Annual UTC Research Day (April 14, 2015). Katrina is pursing her actuarial career at Unum Group (Portland, Maine). Currently,

Micah is pursuing his Ph.D. in statistics at the University of California at Irvine

Dhir is pursuing his Ph.D. in mathematics at The Ohio State University

Huong is pursuing his Ph.D. in mathematics at Duke University
REU Summer 2015. Of the six undergraduate students who joined the REU Summer 2015 program, I mentored

Ethan Addison (Vanderbilt University)

Spencer Smith (Southwest Baptist University)

Richard Vrandenburgh (Tennessee Technological University)
and coauthored a paper in probability theory. In the fall term of 2016,

Ethan will pursue his Ph.D. in mathematics at the University of Notre Dame

Richard will pursue his Ph.D. in mathematics at the University of Virginia
American Mathematics Competitions
The special purpose of the American Mathematics Competitions (AMC) is to stimulate excitement in mathematics and to develop mathematical talent among Chattanooga’s high school students. The department will be sponsoring the AMC 10/12 B on February 17, 2016. Students interested in participating in these contests should contact me and register before January 29, 2016. For banks of previous AMC questions, visit the Art of Problem Solving’s AoPSolving Wiki website. More information on the AMC 10/12B to come soon!
