I am currently a project lead in the Software Development Center at the University of Utah where I work on the development and commercialization of university-related projects.  Prior to that I was the Director of Software Engineering at VisTrails, Inc. a startup company spun out from the university. In 2008, I completed a Ph.D. in Computing from The University of Utah under the direction of Claudio Silva.  I also received an M.S. in Computational Engineering and Science from the University of Utah in 2004 and a B.S. in Computer Science from Utah State University in 2002.

I mainly participated in two research projects during my graduate studies.  The first is the VisTrails, a scientific workflow management system for data exploration and visualization.  The second is Hardware-Assisted Visibility Sorting (HAVS), a volume rendering system for unstructured grids.

My previous professional experience includes five years working at Parametric Technology Corporation as a software engineer on 3D design software and two summers at Lawrence Livermore National Laboratory as a technical scholar.
