Biography

Jennifer Loe is a Senior Member of Technical Staff at Sandia National Laboratories.  She completed her Ph.D. in mathematics at Baylor University in December 2019.  In January 2020, she became a postdoc in the Scalable Algorithms department at Sandia and converted to full staff in February 2022.  Jennifer primarily works in numerical linear algebra, with a focus on Krylov solvers for sparse linear systems.  She is a developer of the Belos package for iterative linear solvers in Trilinos and has also contributed to Kokkos Kernels.  Her research interests include GMRES, polynomial preconditioning, communication-avoiding solvers, and mixed-pecision solvers. When not at work, she enjoys visiting the zoo and aquarium, speaking in Toastmasters, and volunteering for Big Brothers, Big Sisters.
