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 not teaching in Winter 2017.


I am visiting the mathematics department at Harvard University in Spring 2017.
I am speaking at a special session on Arithmetic Dynamics at the Mathematical Congress of the Americas in Montreal in July 2017.
I am speaking at the Young Mathematicians Conference at Ohio State University in August 2017.
I am organizing a small gathering on Braids and Rational Maps with Eko Hironaka at Harvard University in August 2017.
I am speaking at the 13th William Rowan Hamilton Geometry and Topology Workshop at The Hamilton Mathematics Institute in August 2017.
I am speaking at the Midwestern Workshop on Asymptotic Analysis at IUPUI in October 2017.
I am speaking at GROW at Northwestern University in October 2017.
I am attending a conference in memory of my friend Tan Lei at Angers in October 2017.
I am participating in the Workshop on Arithmetic and Complex Dynamics in Oaxaca, Mexico in November 2017.
I am speaking at an AMS sectional meeting on Arithmetic Dynamics, at Northeastern University in April 2018.
