Gaku Liu

Gaku Liu is an Assistant Professor at the University of Washington in Seattle since Fall 2020. His research focuses on geometric combinatorics, including polytopes, triangulations, lattice polytopes, and oriented matroids, with broader interests in graph theory, algebraic combinatorics, and their applications to algebraic geometry, geometric topology, and complexity theory.

He currently holds an NSF grant (DMS-2348785) supporting his work. Lecture notes from his Winter 2020 course on polyhedral combinatorics are publicly available (last updated May 3, 2023).

His CV, detailing publications and full academic trajectory, was last updated in April 2025.
