Bio

Matt Larsen graduated with a Ph.D. in Computer and Information Science from the University of Oregon in December of 2016. Prior to graduation, Matt accepted a full-time staff computer scientist position at Lawrence Livermore National Laboratory, and he continued in this position after graduation. Matt started the Ph.D. program in September 2013, and began his concurrent role at LLNL in January 2016. His research interests include computer graphics, GPU computing, portable performance, and scientific visualization.

Matt worked on two different research grants during his time at UO. His first project was to contribute to the NSF SI2 GraviT project, a ray tracing library for distributed-memory parallel environments. Through this work, he developed a portably-performant ray tracer that was competitive with industry standard ray tracers. This work led Matt to his second project, funded by the Department of Energy XVis grant. With this project, Matt explored the boundaries of portable performance. During his time at LLNL, Matt investigated questions on in situ rendering, which played an important role in his thesis.

Matt's research experience was enhanced by two internships: In 2014, he worked on renderers in the EAVL library at Oak Ridge Laboratory with Jeremy Meredith. Then, in 2015, he worked on lightweight in situ visualization systems at Lawrence Livermore Lab with Eric Brugger.
