About me: I am originally from the north shore of Boston, Massachusetts, and joined the Amherst College Department of Mathematics and Statistics as an Associate Professor in 2014.  I specialize in Number Theory, in particular on modular and mock modular forms, weak Maass forms, q-series, and related objects, with applications to Combinatorics and Lie theory.  Most of my research publications are accessible on this page.  In addition to research, I am actively involved in teaching, mentoring, and mathematics outreach.  In particular, I’m co-creator of S.U.M.R.Y., and have been involved with the Yale National Initiative for public school teachers.  I also regularly advise undergraduate research at Amherst College.  I am grateful for the partial support of a National Science Foundation NSF CAREER Grant (2013-19) for research and outreach.  You can read more about these things by following the links to my research publications, teaching page, CV, and math outreach page, as well as the other links towards the top of this page.
