About me:

I am an associate professor in the Department of Math and Computer Science at Indiana State University. My research interests include complex dynamics, Teichmüller space, self-similar groups, and Thurston's theorem for postcritically finite rational maps. My doctoral thesis was written under the supervision of Kevin Pilgrim at Indiana University. I completed postdoctoral work at Jacobs University and the Institute for Mathematical Sciences and have been a visiting professor at the National Center for Theoretical Sciences in Taiwan.
