I'm a senior research scientist at ICERM and Brown University. I'm supported by the Simon's Collaboration on arithmetic geometry, number theory, and computation. I mostly research analytic number theory, computational number theory and geometry, and arithmetic geometry.
Previously, I was a postdoctoral researcher at the University of Warwick. I received my PhD at Brown University with Jeff Hoffstein as my PhD advisor.
See this page for a broad overview of my research.
