Highlights: Expert in computational plasma physics, fluid mechanics, electromagnetics and thermal physics. Extensive experience with large-scale (100K+ lines of code) massively parallel computational software development.

Research and Professional Experience¶

Associate Research Physicist, Plasma Physics Laboratory, Princeton University (Jan 2012-present)¶

My primary responsibility at Princeton is to develop algorithms for the solution of gyrokinetic equations for tokamak edge simulations. I am also working on understanding the basic formulation of gyrokinetic theory.

Research Scientist, Tech-X Corporation, Boulder Colorado, (April 2006-Dec 2011)¶

Developed finite-volume and discontinuous Galerkin finite-element algorithms for the solution of Maxwell equations of electromagnetism, viscous fluid flow equations including chemical reactions and two-fluid plasma equations.
Created a new C++ library to represent unstructured meshes. Library uses extensive C++ templates to allow use of mixed elements (triangles, quadrilaterals, hexahedra, pyramids and tetrahedra). A powerful sequencing mechanism was implemented for iteration over mesh in a dimensionally and element independent manner.
Incorporated numerical algorithms and mesh library into a new commercial product slated for release in summer of 2011. Worked on user documentation and comprehensive set of examples problems.
Lead development of U.S. Department of Energy (DoE) Scientific Discovery though Advanced Computing (SciDAC) project FACETS, a project to perform full-scale reactor modelling for the U.S. fusion energy program. Press release at http://www.scidac.gov/fusion/fullscale.html. Project website https://facetsproject.org. Wrote core parallel C++/MPI framework and performed first simulations in collaboration with experimentalists.
Presented invited talks at several conferences and published results in computational physics and plasma physics journals.
Wrote proposals and won grants from Department of Defence and Department of Energy for computational physics projects.

Research Associate, University of Washington, Seattle (2001-2006)¶

Developed fluid algorithms for the solution of two-fluid plasma equations and applied them to FRC formation and study of Lower-Hybrid Drift Instability in slab geometries.
Developed solvers for the radiation transport equation in the coupled ocean and atmosphere system. These were applied to study of inverse problems to determine the optical properties of ocean water from remote-sensing and in-situ measurements.

Education and Training¶

Doctor of Philosophy, University of Washington, March 2006.
Master of Science, University of Washington, March 2002.
