Chenyang Xu is a Chinese mathematician in the area of algebraic geometry who works at Beijing International Center of Mathematical Research. In 2016 he was announced as a winner of the ICTP Ramanujan Prize for that year, "in recognition of Xu's outstanding works in algebraic geometry, notably in the area of birational geometry, including works both on log canonical pairs and on Q-Fano varieties, and on the topology of singularities and their dual complexes." He earned his doctorate at Princeton under János Kollár's supervision.
