I am an Associate Professor in the math department at the University of Michigan.


I work primarily in complex analysis, Teichmüller theory, and complex dynamics (in one and several variables).
Here is my CV, and here are my papers.


I am teaching Math 295 in Fall 2020.
I am a faculty advisor for Math Club. It will be online this year - stay tuned! I am a faculty advisor for FEMMES.
I also organize Math Mondays in Ypsi, where a bunch of us do math with students at Ypsi Middle School on Monday mornings. Please email me if you are interested in joining us!

Math Corps:

I am proud to be the Director of the Ypsilanti Math Corps at U(M), a Summer Camp for middle schoolers and high school mentors from the Ypsilanti area. We faithfully follow the educational and mentoring practices of the Math Corps, a phenomenal program that started at Wayne State University in 1992.
Save the dates: This Summer, our camp will run July 13-August 14, 2020.

Upcoming talks and travel:

I am giving a colloquium talk at Dartmouth College in September 2020.
Stephen, Yunus, and I are giving a presentation at the Faculty Forum hosted by the Center for Educational Outreach in October 2020.
I am giving a talk in the ADIOS seminar in December 2020.
I am giving the Dresden Lectures at Swarthmore College in 2020-2021.
I am organizing a semester in Complex Dynamics at MSRI in Spring 2022.
