Dr. Xuening Bai obtained his B.S. in mathematics and physics from Tsinghua University in 2007, and his PhD in astrophysics from Princeton University in 2012. He then moved to Institute for Theory and Computation (ITC) at Harvard-Smithsonian Center for Astrophysics with a joint Hubble Fellow (2012-2015) and ITC fellow (2015-present). He was also appointed as a lecturer at Harvard University in 2015-2016. Dr. Bai is a theoretical and computational astrophysicist. He is primarily interested in planet formation, particularly on the dynamics of gas and dust in protoplanetary disks. He is also interested in several aspects of high-energy astrophysics, including accretion disks, pulsar physics, and cosmic-ray acceleration and transport.
