I am currently a postdoc in the Metric Geometry and Gerrymandering Group at MIT and Tufts, working with Moon Duchin and Justin Solomon on the mathematics of redistricting. Previously, I earned my Ph.D. in mathematics at Dartmouth College under the supervision of Dan Rockmore. 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.### Research Articles
