(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 currently chairing the SIAM Activity Group on Linear Algebra.
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.
