(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 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,
Journal of Numerical Analysis and Approximation Theory (published by the Romanian Academy),
and the SIAM Journal on Matrix Analysis and Applications.

I am the Vice-President at Large of the Society of Industrial and Applied Mathematics (SIAM) [conflict of interest statement]. See my recent blog entry in the SIAM Blogs page.
I am also a member of the Board of Advisors of Accelogic.

Seminars at Temple University.
Applied Mathematics and Scientific Computing at Temple University.
Mathematical Contest in Modeling for undergraduates at Temple.
