Alan Hindmarsh, a mathematician in the Center for Applied Scientific Computing, has been at LLNL since 1968. His research interests include numerical mathematics, numerical methods for ordinary differential equations, stiff systems of differential equations, and mathematical software.

In additon to being a member of the Mathematical Association of America, Alan has also served an associate editor for the *SIAM Journal of Numerical Analysis* and the journal *Applied Numerical Mathematics*.

Alan graduated with honors from Cal Tech in 1964 and earned his Ph.D. in Mathematics at Stanford in 1968. He retired from the Lab in October 2002 but continues to work part time as a Participating Guest.
