I am a fifth year mathematics Ph.D. student in the Algorithms, Combinatorics, and Optimization program at Georgia Tech in Atlanta, USA, working under the supervision of Josephine Yu. Previously, I completed an M.Sc. at McGill University in Montreal, Canada in 2014 under the supervision of Bruce Shepherd. I received my B.Sc. at the University of Victoria in Victoria, Canada in 2012.

My research is primarily in combinatorics and discrete geometry. I am particularly interested in matroids, oriented matroids, tropical geometry, convex geometry, polytopes, and lattices. I am also interested in the interplay between these topics and other areas of mathematics.
