Shiu-Yuen Cheng (鄭紹遠) is a Hong Kong mathematician. He is now Chair Professor of Mathematics at Hong Kong University of Science and Technology. Cheng studied his Ph.D. under Shiing-Shen Chern in University of California at Berkeley.[1] After receiving Ph.D. in 1974, he spent some years as a post-doctoral fellow and assistant professor in Princeton University and State University of New York at Stony Brook. Then he became a full professor at University of California at Los Angeles. Cheng chaired the Mathematics departments of both the Chinese University of Hong Kong and the Hong Kong University of Science and Technology in the 90s. In 2004, he became the Dean of Science in HKUST. In 2012 he became a fellow of the American Mathematical Society.[2]

His research interests encompass Differential geometry, Geometric Partial Differential Equations and Game Theory. His remarkable contributions include comparison theorems of Laplacian eigenvalues on Riemannian manifolds, the maximal diameter theorem in Riemannian geometry.
