Document:
I am a Senior Member of the Technical Staff in the Multiphysics Applications Department, and my main areas of expertise are verification and validation (V&V) and uncertainty quantification (UQ) for numerical simulations. I am also interested in numerical methods for shock-capturing, reactive flows, and data analysis and visualization.
I earned degrees from North Carolina State University (BS, MS) and the University of Minnesota (PhD), all in Aerospace Engineering. My research backround includes compressible fluid dynamics, shock physics, reactive flows, and turbulent flows, and on the numerical methods for simulating them. After a research associate position at the University of Chicago ASC Center on Astrophysical Thermonuclear Flashes, I came to Sandia in 2005.
