Associate Professor Jia Liu
Jia Liu is the Director of Kavli IPMU’s Center for Data-Driven Discovery, where she is implementing new data science techniques like machine learning, and associate professor at Kavli IPMU's CMB Group. Her research deals with large-scale structures of the universe –– dark matter, halos, filaments, and voids. She uses cosmological observations of the cosmic microwave background (CMB) and galaxies together with state-of-the-art numerical simulations to study fundamental physics, such as the nature of dark energy and neutrino mass.
She is a member of Large Synoptic Survey Telescope (LSST), Simons Observatory (SO), Subaru Hyper Suprime-Cam (HSC) and Prime Focus Spectrograph (PFS), LiteBIRD, and CMB-S4. She is currently leading LSST DESC's higher-order statistics topical team international science collaboration and SO's Extragalactic Sky Modeling Foregrounds Analysis Working Group (FG.1).
She has extensively spoken at seminars, conferences and public outreach talks across the globe. Before joining Kavli IPMU, she was Postdoctoral Fellow at the Berkeley Center For Cosmological Physics, UC Berkeley and the Department of Astrophysical Sciences, Princeton University.
She completed her PhD in Astronomy at Columbia University. She also holds an MA in Human Resources & Industrial Relations from University of Minnesota.
