Hannah Hoganson

University of Maryland

I am currently an NSF postdoctoral fellow at the University of Maryland, mentored by Christian Rosendal. Previously, I was mentored by Lei Chen, and a Brin Postdoctoral Fellow, also at UMD. I completed my PhD at the University of Utah in Spring 22. I was advised by Ken Bromberg. I am a topologist interested in geometric group theory, mapping class groups, and applications of descriptive set thoery.

A Word Map

"Word Maps" are a type of element in the mapping class group of a (locally finite) infinite graph. My collaborator Sanghoon Kwak made this great animation of one.
