Why did you decide to 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

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.
