I am currently a research fellow in the School of Mathematics at the University of Bristol. I've previously been a visiting scholar at the University of Washington, a postdoctoral member of MSRI, and a member of the Institute for Advanced Study. Before all that, I was a graduate student at the University of Michigan, where I got my Ph.D. (in 2009) under the supervision of Jeffrey Lagarias. I work primarily in number theory, and I especially enjoy analytic number theory and experimentation.
