(About this photograph, and others)

My interest is Numerical Analysis and Scientific Computing in general, and Numerical and Applied Linear Algebra in particular.

I am chairing the SIAM Activity Group on Linear Algebra through December 2009.
I am chairing the SIAM Committee on Gene Golub SIAM Summer School through December 2014.
I am a member of the Editorial Boards of:
the Electronic Journal of Linear Algebra (ELA),
the Electronic Transactions on Numerical Analysis (ETNA),
Mathematics of Computation,
Numerical Linear Algebra with Applications,
and the SIAM Journal on Matrix Analysis and Applications.

Graduate course Fall 2009: Introduction to Numerical Analysis

Seminars at Temple University.
