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.

Office: Maloney 553

My research interests are in arithmetic geometry and arithmetic statistics.

    This semester I am teaching Calc II (MATH1105). Last semester I taught Calc I (MATH1100) as well as an introduction to p-adic Hodge theory (MATH882201).

    I taught the following classes while at Michigan:
  • Math 115 (Calc I), 3 semesters
  • Math 116 (Calc II), 2 semesters
  • Math 215 (Calc III), 1 semester (as Lab Instructor)
