Lu Wei

Principal Investigator, Ph.D., lwei@caltech.edu

Lu obtained her Ph.D. from Columbia University, working with Prof. Wei Min. Too fascinated by the stimulated Raman scattering microscopy, she decided to stay at Columbia, continuing her postdoctoral work on developing new nonlinear vibrational imaging techniques. Lu joined the faculty at Caltech in 2018. Lu has recently been recognized by the 2017 ACS PHYS Division Young Investigator Award, the 2018 Blavatnik Regional Awards for Young Scientists, the 2019 Amgen Early Innovator Award, and the 2020 NIH Director's New Innovator Award.


Chenxi Qian

Postdoc, Ph.D., cqian@caltech.edu

Chenxi got his Ph.D. from University of Toronto, working with Prof. Geoffrey Ozin. Since very young he has been fascinated by how things work. Driven by his interests in observing informative phenomena in complex materials and biological systems with emerging vibrational imaging methods, Chenxi joined the Wei lab in 2018, trying to obtain more insights into the working principles of these systems. Apart from science, Chenxi loves literature and photography. 


Haomin Wang

Postdoc, Ph.D., haominw@caltech.edu
Haomin graduated as a Ph.D. from Lehigh University. During his Ph.D., he was advised by Prof. Xiaoji Xu on developing novel s-SNOM and AFM-IR methods to reveal details in the nanoworld. Haomin joined the Wei lab in 2020 and is specifically interested in utilizing light-matter interactions as tools to resolve complex systems at fundamental levels. In his free time, Haomin enjoys Karaoke, hiking, and video games. His GOAT game so far is The Legend of Zelda: BotW.
