Xiaoyang Zhu

Xiaoyang Zu's research group is interested in photo-physics in nano, molecular, and hybrid semiconductors and interfaces. They focus on dynamics of quasiparticles (excitons, polarons, polaritons, etc.) and their many-body interactions. These interactions are important to a range of optoelectronic processes, such as solar energy conversion, light emission, and polariton condensation. They employ state-of-the-art experimental techniques, including, among others, time-resolved photoemission spectroscopy, femtosecond nonlinear optical spectroscopies, transient absorption and emission spectroscopies, and two-dimensional spectroscopies

He is the Howard Family Professor of Nanoscience in the Department of Chemistry in the Department of Chemistry and a principal investigator with Columbia's Department of Energy EFRC on Programmable Quantum Materials and Columbia's National Science Foundation MRSEC on Precision Assembled Quantum Materials.
