Patty Hough is a Principal Member of the Technical Staff in the Computational Sciences and Mathematics Research Department at Sandia National Laboratories. She received her B.S. in Mathematics from Lynchburg College in 1991 and her Ph. D. in Applied Mathematics from Cornell University in 1996. Her primary interests include application-dependent fault tolerance and parallel algorithms for nonlinear optimization under uncertainty, and she is currently PI on a number of projects in these areas. She is one of the lead developers for OPT++, a C++ library for nonlinear optimization, and she has organized CSRI-sponsored workshops on fault tolerance that have provided a forum for discussion between the DOE laboratory and university communities.
