Chen-Bo Zhu

Chen-Bo Zhu, also known as Zhu Chengbo (Chinese: 朱程波), is a Singaporean mathematician. Currently he heads the Department of Mathematics at the National University of Singapore. Zhu served as President of the Singapore Mathematical Society from 2009 to 2012 and Vice President of the Southeast Asian Mathematical Society from 2012 to 2013.

In mathematics, Zhu’s work is in representation theory of Lie groups.

Born September, 1964 in Yin County (Chinese: 鄞县, current Yinzhou District), Ningbo, Zhejiang Province in China, Zhu attended Yinzhou High School from 1978 to 1980 and studied mathematics as an undergraduate at Zhejiang University from 1980 to 1984. In 1984, Zhu was among the 15 students nationwide selected by the Government of China and by a joint AMS-SIAM committee for PhD study in the U.S. (Also known as Shiing-Shen Chern Program). Subsequently, he went to Yale University in 1985 and obtained his PhD in 1990, under the direction of Roger Howe. Zhu joined the Department of Mathematics at NUS in 1991, and became a Singapore citizen in 1995.

In representation theory, Zhu’s work is focused on classical groups and their smooth representations. Jointly with Binyong Sun, he has proved multiplicity at most one for branching (also called strong Gelfand pair property) in the Archimedean case, and the conservation conjecture of Stephen S. Kudla and Stephen Rallis. He has also applied Howe correspondence to the structural study of degenerate representations and to the understanding of singularities for infinite-dimensional representations.
