Hi, I’m Lily.

Welcome to my webpage!

I’m a second year PhD candidate in the UMich CSE Theory Group, where I’m fortunate to be advised by Greg Bodwin. My research interests are in combinatorics, particularly structural graph theory and discrete geometry.

Previously, I completed my M.Sc.Eng at UMich in 2021 from the IOE department. Before that, I graduated from UWaterloo in 2020 with a B.Math in Pure Math and Combinatorics & Optimization.
