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 296 in Winter 2019.
I am a faculty advisor for Math Club. (Stop by! It's on Thursdays at 4pm in the Nesbitt room.)
I am also a faculty advisor for FEMMES, and I like to help out with Wolverine Pathways.
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!

Upcoming talks and travel:

I am giving a talk about the work of Maryam Mirzakhani, to celebrate women in mathematics, at MSRI in May 2019.
I am going to Toulouse to work with Xavier in May 2019.
I am speaking at the Geometric Topology, Geometric Group Theory and Dynamical Systems Conference at the Inter-University Centre in Dubrovnik, Croatia in June 2019.
Stephen, Yunus, and I are starting a Math Corps site at U(M) this Summer!
I am speaking at AGNES at Boston College in September 2019.
I am giving a colloquium talk at Vanderbilt University in October 2019.
I am organizing the Illustrating Dynamics and Probability workshop as part of a semester on Illustrating Mathematics at ICERM, together with Jayadev Athreya and Alex Holroyd, in Fall 2019.
I am speaking at the 19th International Fibonacci Conference, at the University of Sarajevo, in July 2020.
I am organizing a semester in Complex Dynamics at MSRI in Spring 2022.
