Chen Greif is Professor and Head of the Department 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 in San Jose, California (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. Chen publishes research articles primarily in top numerical journals,
and has given several plenary lectures in major
conferences. He presently serves as SIAM Secretary, and is a member of the SIAM Council. He serves as Chair of the SIAM Committee on Committees and Appointments
and is an associate editor of the SIAM Journal on Scientific Computing. He is also on the editorial board of the Computational Science and Engineering book series, and is a member of the SIAM Book Committee.
In 2014-2017 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 (2015).
