Welcome!

I am an Arthur F. Thurnau Professor in the math department at the University of Michigan.

Research:

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.

Teaching:

I am teaching Math 636, on the Topology and Dynamics of Rational Maps, in Fall 2025.
I am a faculty advisor for Math Club, and I help organize Bagel Sundays - stop by!
I am also a faculty advisor for the student group FEMMES - check out all of the awesome things they are doing!
I also organize Math Mondays in Ypsi, where a bunch of us do math with students at Ypsi Community Middle School on Monday mornings. Our visits to the middle school have been temporarily replaced by virtual Super Saturdays. If you are interested in joining us, please email me!
Stephen and I organize Michigan Math Circle and Washtenaw and Wayne County Math Teachers' Circle! Check them out!

Math Corps:

I am proud to be the Director of the Math Corps at U(M), a summer camp for middle schoolers and high school mentors from Ypsilanti and Detroit. We faithfully follow the educational and mentoring practices of the Math Corps, a phenomenal program that started at Wayne State University in 1992. (Watch the video or the clip!).
Purchase a Michigan Math hoodie to help support the Math Corps! Be sure to check in with our hoodie store frequently as we will often change our colors up!

Upcoming talks and travel(?) :

I was very excited to help organize the Marjorie Lee Browne Colloquium on MLK Day 2023!! Check out the recording!!
I helped to organize Dynamical Developments: Degenerations of Flat Surfaces and Rational Maps, a conference that celebrates JHH80 (!!) in Toulouse in June 2025.
I hope to organize a complex dynamics conference in Boston with my buddy, Dylan Thurston in December 2025.
I will spend the spring 2026 semester at Harvard.
I am headed to Stony Brook to give a talk in spring 2026.
