Mark holds a B.S. in mathematics from Brown University (2006) and an M.S. in computer science from UC Berkeley (2009). In his previous research, he has fabricated mathematical artwork, designed visualization tools, and investigated how people use technology to learn about mathematics and science. His recent projects at LBNL include profiling and improving collective I/O performance on NERSC's flagship Cray XT4 system, tuning image processing filters for multicore processors and GPUs, and researching parallelization strategies for visualization algorithms.
