Chen Greif is a professor and former department head of computer science at the University of British Columbia. In March 2022 he was elected a fellow of the Society for Industrial and Applied Mathematics for "contributions to scientific computing, especially in numerical linear algebra and its applications."^[1]

Greif attended Tel Aviv University, earning a bachelor's degree 1991 and a master's degree in 1994 in mathematics. He continued his education at the University of British Columbia, where he was awarded a PhD in Applied Mathematics in 1998. He was also a postdoctoral fellow at Stanford University from 1998 to 2000.^[2]

His research is primarily concerning scientific computing and more specifically:

• Matrix theory and analysis
• Iterative solvers and preconditioning techniques for sparse linear systems
• Saddle-point linear systems
• Numerical solution of elliptic partial differential equations
• Linear algebra aspects of constrained optimization problems
