Prof. Sijie Gao graduated from the Department of Physics, University of Chicago, USA in 2002. From 2002 to 2005, he was a postdoctoral fellow at the Instituto Superior Tecnico (Lisbon, Portugal). Since 2005, he has been an associate professor and professor in the Department of Physics, Beijing Normal University. For many years, he has been engaged in fundamental theoretical research on general relativity and black hole physics, including weak cosmic censorship hypothesis, black hole thermodynamics, the principle of maximum entropy in curved spacetime, thin shell models, light rings outside a star and black hole, etc. Since 2007, he has been the leader of four projects supported by National Natural Science Foundation of China (NNSFC). He was also selected as one of the "New Century Excellent Talent Support Program" by the Chinese Ministry of Education in 2012. In 2020, he was invited to be the editorial board member of Classical and Quantum Gravity, an international academic journal.

Areas of Research:

He has been focusing on theoretical research in general relativity and black hole physics, including the of weak cosmic censorship hypothesis, black hole thermodynamics, the principle of maximum entropy in curved space-time, thin shell models in general relativity, properties of light rings, etc..
