About Nathan Ryan

I have been at Bucknell since 2007. I spent Fall 2009 in Uruguay as the recipient of a Fulbright grant and I spent Fall 2017 in Ecuador as the recipient of a Fulbright grant, as well. I spent Spring 2011 at the MSRI and my sabbatical year in 2013-2014 in Uruguay.

Educational Background

  • Dartmouth College, Ph.D.
  • Dartmouth College, M.A.
  • Bard College, B.A.

Research interests

I have two parallel research programs. I prove theorems, develop algorithms and carry out computations related to modular forms and L-functions. With students, I work on data science projects from a variety of areas (healthcare, transportation, film and media studies, etc.)

Teaching Interests

I teach a variety of classes in the department and am particularly drawn to two kinds of classes: (1) courses that can naturally be built around projects (preferably community based ones) and (2) courses that show students the explanatory power of mathematical reasoning.
