Yat-Sun Poon


Professor Yat-Sun Poon (潘日新) is a professor of the Mathematical Sciences Center of Tsinghua University.


He received his undergraduate education at the Chinese University of Hong Kong (1977-1981). Supported by the Croucher Foundation Scholarship, he pursued a D.Phil degree in St. Catherine College of Oxford University (1981-1985), under the supervision of Nigel J. Hitchin.


Between 1985 and 1987, he was a NSF post-doctoral fellow under the supervision of Blaine Lawson in the State University of New York at Stony Brook. In 1987, he became an assistant professor at Rice University. In 1991, he became an associate professor of the University of California at Riverside. By 1995, he was promoted to be a professor. From 2000 to 2004, he served as an associate dean to oversee the division of physical and mathematical sciences of the College of Natural and Agricultural Sciences. In 2008, he was appointed a distinguished visiting professor by the Mexican Academy of Sciences.


In his earlier career, Professor Poon applied algebraic geometric techniques to investigate problems in differential geometric objects such as the existence of self-dual metrics and quarternionic Kahler manifolds. In recent years he studies deformation of geometric objects, mostly in the context of generalized complex structures.
