David Hsieh

David Hsieh is the Donald A. Glaser Professor of Physics and Executive Officer for Physics at the California Institute of Technology, affiliated with the Division of Physics, Mathematics and Astronomy. He holds a B.S. from Stanford University and a Ph.D. from Princeton University. Hsieh served as an Assistant Professor at Caltech from 2012 to 2018, was promoted to Professor in 2018, and became the Glaser Professor in 2022. He has also held the role of Executive Officer since 2023. His research interests are in physics.

David Hsieh is a physicist whose research focuses on topological insulators and quantum materials. His work explores the properties of topological insulators, including their surface states, spin textures, and Dirac fermions. He investigates phenomena such as quantum spin Hall effects, chiral spin textures, and time-reversal protection. Hsieh also examines the interplay between symmetry, topology, and electronic properties in materials like perovskites and correlated iridates. His research includes the study of nonlinear optical responses and the development of quantum materials with tunable properties. His work contributes to understanding the fundamental physics of topological phases and their potential applications in spintronics and quantum technologies.
