Research Interests

I am currently an Assistant Professor of Data Analytics in the Department of Mathematics and Statistics at Washington State University. Previously, I was a postdoctoral associate at MIT (CSAIL) in the Geometric Data Processing Group, working under Justin Solomon and associated with the Metric Geometry and Gerrymandering Group at MIT and Tufts, working with Moon Duchin and Justin Solomon on the mathematics of redistricting. I earned my Ph.D. in mathematics at Dartmouth College under the supervision of Dan Rockmore in 2018. My research interests tend towards applications of algebraic and combinatorial methods in data analysis.

Croasdale Award

In 2018, I won the Hannah Croasdale Award, which is a college-wide award awarded annually to the graduating PhD recipient who best exemplifies the qualities of a scholar. An article from the graduate school focused on my research experiences can be found: here.
