Chen Greif is a Professor in 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 arising from partial differential equations or constrained optimization problems.
Chen is SIAM Fellow (Class of 2022) and the recipient of the Canadian Applied and Industrial
Mathematics Society's Research Prize (2023).
He is a co-author (with Dr. Uri Ascher) of the SIAM bestselling book,
A First Course in Numerical Methods,
and has co-authored or co-edited two other books.
He publishes research articles primarily in numerical journals,
and has given several plenary lectures in major
conferences.
He is Section Editor of Numerical Algorithms for Scientific
Computing in the SIAM Journal on Scientific Computing, and is also on the editorial board of the SIAM Computational Science and Engineering book series.
Chen served a two-year term (2018-2019) as SIAM Secretary, was Chair of the Gene Golub SIAM Summer School Committee (2014-2017), and has held other leadership roles in SIAM in the past few years.
Among major conference organization roles, Chen was Chair of the Organizing Committee of the International Conference on Preconditioning Techniques for Scientific and Industrial
Applications (2017) and co-Chair of the SIAM Conference on Applied Linear Algebra (2015).
Chen was the Head of the Department of Computer Science of UBC for five years from 1/1/2016 to 12/31/2020, and Interim Head for six months from March through August, 2023.
He has received four departmental teaching awards for scientific computing courses that he has taught at UBC.
Prior to taking on his 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).
