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 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 approximately 40 research articles in top numerical journals, and has given several plenary lectures at major
conferences in numerical linear algebra. Chen presently
serves as an associate editor of the SIAM Journal on Scientific Computing (since 2011), and is a member of the editorial boards of the SIAM Book Committee and the Computational Science and Engineering book series.
He is Chair of the Gene Golub SIAM Summer School Committee, and has served on several program committees.
Among his recent 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 latest SIAM Conference on Applied Linear Algebra (2015).
He is formerly the Program Director of the SIAM Activity Group on Linear Algebra (2010-2012), and has served on various other leadership roles in the scientific community.
