My interest is Numerical Analysis and Scientific Computing in general,
and Numerical and Applied Linear Algebra in particular.
I am a co-Director of the
High-Performance Computing for Scientific Applications Professional Science Master,
and a member of the
Center for Computational Mathematics and Modeling at Temple University.
I am a member of the Editorial Boards of:
The
Electronic Journal of Linear Algebra (ELA),
the
Electronic Transactions on Numerical Analysis (ETNA)
(
European mirror site),
Linear Algebra and its Applications,
Mathematics of Computation,
Numerical Linear Algebra with Applications,
and the
Journal of Numerical Analysis and Approximation Theory
(published by the Romanian Academy).
I am currently the
President of the
International Linear Algebra Society (ILAS)
and the chair of the Selection Committee for the AWM Dissertation Prizes.
