Jennifer first came to Sandia National Labs as a student intern in Summer 2017.  She then joined as a Postdoctoral Associate in January 2020.  Her research interests are in numerical linear algebra, Krylov solvers, polynomial preconditioning, communication-avoiding solvers, and multipecision solvers.  Her current work is funded by the ECP SAKE (Solvers and Kernels for Exascale) and Multiprecision projects.  She also helps to develop the Belos linear solvers package in the Trilinos software library.
