Jeffrey is currently a Post Doctoral Research Associate at Lawrence Livermore National Laboratory. He is working in the Center for Applied Scientific Computing studying various a posteriori error estimation techniques for uncertainty quantification. Jeffrey is interested broadly in numerical methods for partial differential equations with applications to problems in fluid dynamics and climate science.

Jeffrey received his Ph. D. from the Department of Mathematics at the University of Pittsburgh in 2010. As a graduate student he studied topics in scientific computing under advisor William J. Layton. His dissertation work focused on stable decoupling methods for atmosphere-ocean interaction. He also received his B. S. Engr. at the University of Pittsburgh in 2003 in Engineering Physics.
