Brief Introduction of Professor Shicheng Wang

Dr. Shicheng Wang is a mathematician and an academician of the Chinese Academy of Sciences (CAS). He is a professor and doctoral supervisor at the School of Mathematical Sciences at Peking University, as well as the director of the Institute of Mathematics at Peking University. After obtaining his master's degree from Peking University in 1981, he became a faculty member at the university. In 1988, he earned his Ph.D. from the University of California, Los Angeles, USA.In 1998, he was awarded the Shiing-shen Chern Prize in Mathematics. From 1999 to 2008, he served as the deputy director of the Institute of Mathematics at Peking University. He was an invited speaker at the International Congress of Mathematicians (ICM) in 2002, and was elected as an academician of the Chinese Academy of Sciences in 2005 and served as the Chairman of the 11th Council of the Chinese Mathematical Society from 2012 to 2015.

Dr. Wang’s main research focus lies in low-dimensional topology, encompassing areas such as geometric group theory, fixed point theory, dynamical systems, and algebraic topology. He has achieved the following major results with his collaborators: the discovery of the first example that an immersed essential surface in a 3-manifold cannot be lifted to a surface embedded in a finite covering; the observation of obstructions to cyclic surgeries on satellite knots, along with a proof of the finiteness of the number of boundary slopes of immersed essential surfaces in a hyperbolic 3-manifold; and creative research in areas including finite group actions, chirality, manifold embeddings, and constraints between attractors and manifold topology. Particularly noteworthy is his pioneering work in the mappings between 3-manifolds, which includes a series of insightful and significant contributions to the exploration of the uniqueness of the degree of covering maps, the existence, finiteness, standard types of non-zero degree maps and their interactions with 3-manifold topology.
