I am currently an Assistant Professor in the Department of Mathematics at the University of Rhode Island. Starting Fall (autumn) 2018, I am also the Graduate Director of Mathematics at URI.
I was previously a Milnor lecturer at Stony Brook University.

My research is mainly focused on one-dimensional holomorphic dynamics, in particular Thurston equivalence of rational maps, matings of polynomials and the study of spaces of rational maps. I am also interested in related subjects, such as Teichmüller theory, Riemann surface theory and topological dynamics.

Araceli Bonifant and I have set up a Dynamics seminar at URI. Here is the web page for the dynamics group.



I am also investigating combinatorial invariants of (bicritical) rational maps, and studying slices of the parameter space of cubic rational maps.
In preparaton
I am also studying the symmetry locus (maps of the form f(z)=c(z + 1/z)) in the space of quadratic rational maps with Sarah Koch and Kathryn Lindsay.
My thesis which I completed at the Mathematics Institute at the University of Warwick. My advisor was Adam Epstein.

Posters, talks etc.


In Spring 2020, I am teaching

My office hours are: I am also teaching independent study courses on Holomorphic Dynamical Systems.
