Siqing Zhang

Siqing Zhang is a Gibbs Assistant Professor at Yale University, where he conducts research in algebraic geometry. From 2023 to 2025, he is a Postdoctoral Member at the Institute for Advanced Study (IAS), mentored by Bhargav Bhatt. He completed his Ph.D. at Stony Brook University in 2023 under Mark Andrea de Cataldo and holds a B.S. in Mathematics and Philosophy from NYU Shanghai (2018).

Research Interests: Dr. Zhang's work bridges algebraic geometry, arithmetic, and topology. His research focuses on moduli stacks, characteristic p geometry, perverse sheaves, and geometric applications to the P=W conjecture and non-Abelian Hodge theory. He explores phenomena in positive characteristic, including harmonic metrics, liftings mod p², and logarithmic poles.

Publications: His recent articles address cohomological structures in positive characteristic, semistability in non-Abelian Hodge theory, and moduli spaces for Higgs bundles and t-connections. These studies often intersect with geometric invariant theory, algebraic stacks, and topological methods in algebraic geometry.

Scientific Contributions: Dr. Zhang has been invited to speak at institutions like the Simons Center, Harvard-MIT, and Clay Mathematics Institute on topics including étale homotopy, non-Abelian Hodge theorems, and characteristic p geometry.
