  Weizhu Bao (Chinese: 包维柱, born September 1969 in Shaanxi, China) is a Chinese mathematician at the National University of Singapore (NUS). He is known for his work in applied mathematics with applications in quantum physics and chemistry and materials science, especially Bose-Einstein condensation (BEC) and highly oscillatory partial differential equations.
  
  ## Biography
  
  Bao was born in Xunyang County, Shaanxi Province, China. He completed his undergraduate studies in the Department of Mathematics at Tsinghua University in 1992 and obtained his master's degree and Ph.D. degree under the advice of Houde Han in the Department of Mathematical Sciences at Tsinghua University in 1995. He was subsequently a faculty member at Tsinghua University (1995-2000) with various visiting positions at Imperial College (1996 — 1997), Georgia Institute of Technology (1998 — 2000) and University of Wisconsin at Madison (Sept—Dec, 2000) during the period. He joined the National University of Singapore as an assistant professor in 2001 and became a full professor in 2009.
  
  ## Contributions
  
  Bao has made contributions to Bose-Einstein condensation (BEC), multiscale methods, computational quantum physics and chemistry, computational fluid dynamics, and computational materials science. In the study of BEC, he and collaborators have established mathematical theory and proposed efficient and accurate computational methods. For highly oscillatory partial differential equations, he and collaborators have developed the uniformly accurate multiscale time integrator method. For solid-state dewetting, he and collaborators have derived sharp interface and phase field models.
