Assistant Professor, Mathematics and Statistics

Dr. Gillespie primarily teaches analysis and statistics-related courses, including mathematical programming and elementary number theory. He specializes in analytic number theory and statistics including zero distribution of automorphic L-functions and related prime number theorems.

Dr. Gillespie is a member of the American Mathematical Society.

## Education and Training

- PhD, University of Iowa, Iowa City
- BS/BA, St. Ambrose University

*Why did you study math?*

I studied mathematics because I felt like it was a language that I could never learn by myself, and that becoming fluent in it would open up doors to many of the other sciences
