Younghan Bae

Younghan Bae is a Donald J. Lewis Research Assistant Professor at the University of Michigan's Department of Mathematics. He holds visiting fellow status at the Korea Institute for Advanced Study (KIAS). His research focuses on moduli spaces in algebraic geometry, including Calabi-Yau 4-folds, intersection theory, and Picard stacks. Bae completed his Ph.D. at ETH Zurich (2023) under Rahul Pandharipande, with prior degrees from Columbia University (M.S., 2018) and Seoul National University (B.S., 2017).

Research emphases include Donaldson-Thomas theory, Gromov-Witten theory, and the study of moduli spaces of sheaves. His work bridges geometric and arithmetic aspects of algebraic structures. Recent papers explore DT/PT0 correspondences in Calabi-Yau geometries and Abel-Jacobi theory on Picard stacks.

Organizational contributions include co-organizing Geometry meet physics: Calabi-Yau fourfolds and beyond and Moduli spaces of algebraic surfaces in Ann Arbor. His expository work includes a chapter in the KIAS Springer Series on sheaf counting theories.
