Joseph Gunther

I'm a mathematician, doing research in number theory and algebraic geometry, with a particular emphasis on arithmetic statistics.
In January 2018, I started a three-year postdoctoral position at Université Paris-Sud (Paris 11/Orsay), with François Charles. Before that, I was a postdoc at University of Wisconsin-Madison for the Fall 2017 semester. You can contact me at jgunther7 AT gmail dot com. I like reading preprints, so feel free to send them along.

I received my Ph.D. in June 2017 from City University of New York (CUNY); my advisor was Lucien Szpiro.
