I am a researcher in the Scalable Algorithms Department in the Center for Computation, Computers, Information, and Mathematics (CCIM) at Sandia National Laboratories.

Education

• M.A., Ph.D. in Mathematics, University of Kentucky
• B.A., Lawrence University

Research Interests

My main interest is scalable solution methods for linear systems, such as multigrid methods. I am a developer of the ML preconditioner library, which provides robust algebraic multigrid preconditioner methods for a variety of problem types. ML is part of Sandia's flagship numerical algorithms framework, Trilinos.
