Bio
I'm a Graduate Research Assistant at the Scientific
Computing and Imaging Institute at the
University of Utah, working
with Valerio Pascucci.
Before joining the Ph.D. program at Utah I obtained a B.S. in
physics with a minor in computer science at the
University of California, Riverside in 2014.
My research interests cover a range of areas in scientific visualization and
computer graphics including: distributed rendering, virtual reality,
in situ visualization and ray tracing.
