Ari Shnidman

I am a postdoc in the Boston College math department.
I received my Ph.D. from the University of Michigan in May 2015.   My advisor there was Kartik Prasanna.

I am currently applying for tenure-track positions (Fall 2017).

Office: Maloney 553

My research interests are in arithmetic geometry and arithmetic statistics.
