General Information

I received my Ph.D. in mathematics from the University of Illinois at Urbana-Champaign 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 Assistant Professor of Mathematics.


Area of Research

My area of research is in number theory. My favorite topics are L-functions, prime numbers, and Farey fractions. I have worked, also, in probability theory, especially random polynomials.


Teaching Assignments

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

  • MATH 4270/5270 (Elementary Number Theory)

In the fall I will be teaching

  • MATH 1950 (Calculus with Analytic Geometry I)

  • MATH 3510 (Introduction to Analysis I)

  • MATH 4995 (Departmental Thesis)


Master's Students

  • Ashley Holcombe (May 2014)

  • Gentry Jones (December 2014)

  • Benjamin Kimsey (December 2014)


Undergraduate Students

  • Melissa Miller (May 2016)


Student Problem Competition

The Student Problem Competition is an ongoing competition for mathematics majors, mathematics minors and mathematics enthusiasts. A prize of $20.00 is awarded to the student who successfully solves the problem and provides the best correct solution with all assertions proved.


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 2013-2015 (NSF Grant DMS-1261308). In the summer of 2013 nine undergraduate students participated in the REU program. Of these, I mentored

  • Kathryn Crosby (Oral Roberts University)

  • Jordan Eliseo (University of North Carolina at Greensboro)

  • David Mazowiecki (William Paterson University)

in number theory. Last summer nine energetic undergraduate students also participated. I mentored

  • Katrina Ferrier (University of Tennessee at Chattanooga)

  • Micah Jackson (Georgia Southern University)

  • Dhir Patel (Rutgers University)

  • Huong Tran (Georgia Institute of Technology)

in probability theory. Dhir and Huong presented a 20 minute report talk at the Young Mathematicians Conference at Ohio State University (August 22-24, 2014). Katrina presented a 20 minute talk at Western Kentucky University's 34th Annual Mathematics Symposium, a research poster at the Emory University-Laney Graduate School STEM Research and Career Symposium (March 25-27, 2015) and a research poster at the 7th Annual UTC Research Day (April 14, 2015). This fall Micah will be pursuing his Ph.D. in statistics at the University of California at Irvine, Dhir will be pursuing his Ph.D. in mathematics at the Ohio State University, and Huong will be pursuing his Ph.D. in mathematics at Duke University.
