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 and Math 312 in Fall 2018.
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. Please email me if you would like to help run a math circle at the FEMMES Capstone on Nov 10, or at Wolverine Pathways on Saturdays running from Oct 6-Nov 17.

Upcoming talks and travel:

I am giving a colloquium talk at the University of Washington in October 2018.
I am organizing the Graduate Research Opportunities for Women conference, at the University of Michigan, together with Karen Smith and Mel Hochster, in October 2018.
I am visiting the National Science Foundation in December 2018.
I am giving an AMS-MAA Invited Address at the Joint Math Meetings in Baltimore in January 2019.
I am visiting the Math Department at Harvard University in January 2019.
I am running a math circle for teachers in February 2019.
I am speaking at the Arithetmic Dynamics Special Session at the AMS Meeting at the University of Hawaii in March 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.
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.
