I am an NSF Postdoctoral Fellow at Carnegie Mellon University, working in combinatorics and discrete geometry, with Florian Frick as my sponsor. In 2021 I completed my PhD at the University of Washington under Isabella Novik.

My research focuses on the relationship between geometric and combinatorial objects. I am interested in geometric realizations of combinatorial objects, especially realizations that are minimal, usually with respect to dimension. In the other direction, I work to understand the combinatorial properties of geometric objects, such as their enumeration up to combinatorial equivalence or combinatorial decompositions induced by geometric operations.

OTHER ACTIVITIES   (return to top)
During my graduate studies I was an active organizer and Joint Council member with UAW4121, the union of academic workers at the University of Washington. I am proud to have taken action alongside fellow grad students and workers to win fully-subsidized transit passes, strong protections from harassment, trans-inclusive healthcare measures, improved mental health care, and other crucial gains. I was also active in grassroots political organizing, for example volunteering with the Tax Amazon movement, which won hundreds of millions of dollars in funding for affordable housing in Seattle. In Pittsburgh I have been active in organizing community support for labor campaigns, for example Amazon workers who are fighting for a union at Amazon's KCVG air hub. More recreationally, I enjoy hiking, rock climbing, cooking, and parkour.
