Carolyn Chun's Research

In 2022, I officially joined the research group of Professor Tim Koeth at University of Maryland, in the Department of Materials Science and Engineering, as the Head of Simulations for the Koeth Group, which consists of a few professors, a few professionals, a few graduate students, and several undergraduate students (pictured below).  This is an exciting addition for me to my pure mathematics work in graphs, matroids, polymatroids, and delta-matroids.  It's always the right time to learn something new! 
 
Here is a link to a page with more information about bulk electrets, one of my current projects with the Koeth Group.
