Prof. Meng Gu is an Assistant Professor in the Department of Physics at the University of Hong Kong. Before joining HKU, she was a postdoctoral fellow at Carnegie Observatories, and a Henry Norris Russell postdoctoral fellow in the Department of Astrophysical Sciences at Princeton University. She is an observer and a specialist in stellar population synthesis modeling. Her research focuses on galaxy formation and seeks to understand the physical mechanisms driving the complicated interplay between star formation and galaxy mass assembly. 

Prof. Gu's research addresses several unresolved questions in the field: What is the stellar initial mass function of galaxies, how does it vary globally and locally, and what is the implications on the mass measurement? She also explores the role of environmental factors in shaping galaxy formation and evolution. How do massive galaxies grow, and what can we learn from the spatial information of stellar populations? She has used observations from the Magellan Telescopes, ESO's Very Large Telescope (VLT), and the Sloan Digital Sky Surveys to tackle these questions. Moving forward, she will further her research using the next-generation observing facilities, such as the James Webb Space Telescope (JWST) and the Subaru Prime Focus Spectrograph (PFS) survey.
