Here is a flyer advertising the graduate class "Polyhedra in the Wild" that I taught in Spring 2016, and the main course page.

I also supervised a project in the Illinois Geometry Lab titled "Discrete Morse Theory, Vector Fields, and Materials Science" that is continuing in the fall. Please see their website for information about applying to IGL projects, though emails asking me about my Fall 2016 projects are welcome.

In 2014, I received my Ph.D. from the Mathematics department at North Carolina State University under the supervision of Patricia Hersh and Seth Sullivant.

In 2009, I received my B.S. in Mathematics at the University of Washington, Seattle. My undergraduate thesis supervisor was Sara Billey.

In 2006, I received my A.A. from Seattle Central College, formerly known as Seattle Central Community College.

With Elizabeth Drellich I am organizing a Minisymposium at the SIAM Conference on the Life Sciences , July 11-14 2016, Boston, MA

With Alex Yong and Laura Escobar Vega I am co-organizing the University of Illinois Algebra-Geometry-Combinatorics Seminar. In Fall 2016 we will meet Fridays 4-4:50 pm in a room TBA. Titles and Abstracts can be found here.
