Prof. Jianfeng Wu earned his bachelor (2003) and master (2006) degrees from Tsinghua University. Then he moved to The Pennsylvania State University in USA, obtaining his PhD degree in 2012. He did postdoctoral research afterward at Harvard-Smithsonian Center for Astrophysics and University of Michigan. In 2017 he was selected by the national "Youth Thousand Talents" program and became a professor at Dept. of Astronomy in Xiamen University. His research area covers black holes across the mass scale, studying both physical properties of black holes (e.g., measurement of mass and spin) and their cosmological evolution (e.g., high-redshift quasars). He is specially interested in multiwavelength data analysis and large scale surveys.
