My background is in the design of electronic excited state materials using a union of experimental nonlinear optical spectroscopy, instrument simulation and modeling, and quantum chemical methods. I extended my work to vibrational materials and neutron scattering methods upon moving to Caltech in 2002, and to experimental time-resolved Raman scattering in 2006. I served as a Lead Software Developer and the Project Manager for a $15M NSF funded project on computational neutron scattering from 2006 to 2012. I was employed by Enthought, Inc in 2012. I am a co-founder of the UQ Foundation for the advancement of predictive science.

I am currently based in the Center for Advanced Computing Research at Caltech, and have been developing publicly-released software to support research in predictive science and high-performance computing since 1998. I am the primary author of the software framework for uncertainty quantification (mystic) used by the $17M Caltech PSAAP Center for the Predictive Modeling and Simulation of High-Energy Density Dynamic Response of Materials, the $4M LANL Exascale Co-Design Center for Materials in Extreme Environments, and several other smaller DOE and DOD projects. Other software for which I am the primary author include pathos, dill, pyIDL, and pygrace.

I have over fifteen years of teaching experience, have given over a hundred conference and workshop presentations, and have taught both introductory and advanced python to thousands of students.
