I am an Assistant Professor of Mathematics at the United States Naval Academy.
I finished my Ph.D. in Mathematics at Washington University in St. Louis in May 2016, and my dissertation can be found here (more up-to-date content is in the articles listed below). After that, I was a Zuckerman STEM Postdoctoral Fellow at Technion-Israel Institute of Technology for two years, and then I was a Department Postdoctoral Fellow at the University of Waterloo for another two years. I joined the USNA mathematics department in July 2020.
