Chen Greif is Department Head and Professor of Computer Science at the University of British Columbia in Vancouver, Canada.
His main research area is numerical linear algebra, within the field of scientific computing and numerical analysis. He specializes in preconditioning
techniques for iterative methods for solving large and sparse linear systems.
Prior to taking on a professorial position with UBC (2002), he was a senior software engineer at Parametric Technology Corporation (2000-2002)
and a postdoctoral fellow at Stanford University (1998-2000). He is a co-author (with Dr. Uri Ascher) of the SIAM bestselling book,
A First Course in Numerical Methods,
and a co-editor of two other books. He has published research articles primarily in top numerical journals,
and has given several plenary lectures in major
conferences in applied linear algebra. Chen presently serves as SIAM Secretary, and is a member of the SIAM Council. He also serves
as an associate editor of the SIAM Journal on Scientific Computing (since 2011), is on the editorial board of the SIAM Book Committee and the Computational Science and Engineering book series, and is a member of the SIAM Book Committee.
Until 2017 he was Chair of the Gene Golub SIAM Summer School Committee, and he was previously the Program Director of the SIAM
Activity Group on Linear Algebra (2010-2012).
Among his recent major conference organization roles, Chen was Chair of the Organizing Committee of the latest International Conference on Preconditioning Techniques for Scientific and Industrial
Applications (2017) and co-Chair of the SIAM Conference on Applied Linear Algebra in 2015.
