Xu-Jia Wang (Chinese: 汪徐家; born September 1963) is a Chinese-Australian mathematician. He is a professor of mathematics at the Australian National University and a fellow of the Australian Academy of Science.
Wang was born in Chun'an County, Zhejiang province, China. Wang obtained his B.S. in 1983 and his Ph.D. in 1990 from the Department of Mathematics of Zhejiang University (ZJU) in Hangzhou.
After completing his PhD, Wang served as lecturer and associate professor, at ZJU before departing for ANU In 1995. Wang is a Professor in the Centre for Mathematics and its Applications and Mathematical Sciences Institute of Australian National University.
Wang is well known for his work on differential equations, especially non-linear partial differential equations and their geometrical and transportational applications. Australian mathematician Neil S. Trudinger is his longtime collaborator.
