Professor Garthwaite also chairs the Honors Council.

Educational Background

  • Ph.D. in Mathematics, University of Wisconsin
  • M.A. in Mathematics, University of Wisconsin
  • B.S. in Mathematics, Pennsylvania State University Schreyer's Honors College

Research Interests

  • I study Additive Number Theory, which means that I study numerical
    patterns and special functions that arise in other areas of mathematics and science. My focus
    is automorphic forms, which are functions with interesting symmetry properties, and I use
    methods from combinatorics and analysis. Particular interests include:
    • Modular and mock modular forms
    • Partitions
    • Hypergeometric series

Teaching Interests

  • I enjoy teaching a variety of introductory and special topics courses. My particular area of emphasis is number theory, which has applications to cryptography. In 2010 and 2012 I taught a Foundation Seminar entitled \Visual and Mathematical Patterns" looking at the interplay between mathematics and art.
