Samuel is in his fourth year as a Ph.D. student in the Computer Science Department at the University of Oregon. He also holds a concurrent role as a staff computer scientist at the National Center for Atmospheric Research, as of September 2016. Samuel's research focuses on novel ways to represent and compress scientific data for visualization purposes, especially in relation to exascale computing. Currently, Samuel is investigating the usage of wavelet compression and state-of-the-art encoders from the image processing community.

Prior to joining UO, Samuel completed an M.S. degree from Tufts University, working with Remco Chang. His M.S. thesis was published as a research paper, Exploring Visualization Designs Using Phylogenetic Trees, at the SPIE Visualization and Data Analysis conference in 2015, and won a Best Paper award. During his time at UO, Samuel collaborated with John Clyne of NCAR, first as a summer student in 2015, and later through NCAR's Advanced Study Program (ASP) Award in Winter of 2016. Finally, Samuel did an internship at Los Alamos National Laboratory in the Summer of 2016, working with Chris Sewell, Ollie Lo, and Jon Woodring.
