Mark is a Distinguished Engineer in the High Fidelity Physics research group. Mark has over 25 years of experience building GPU-accelerated software for graphics, physically-based simulation, data science and other applications. Mark’s PhD in Computer Science from the University of North Carolina at Chapel Hill focused on real-time simulation and rendering of clouds using General-Purpose computing on GPUs (pre-CUDA).

Mark joined NVIDIA in 2003, originally as a Developer Technology Engineer supporting games and graphics developers in Europe. Mark contributed to the launch of CUDA, founded devblogs.nvidia.com, and has taught thousands of developers about CUDA through numerous blog posts, presentations and tutorials. From 2018 to 2024 Mark worked on RAPIDS, a GPU-accelerated data science suite, where he helped lead development of RMM (memory manager library), libcudf (data frames), cuSpatial (geospatial analysis), and cuProj (geodetic/map projections). Mark lives with his family in the Northern Rivers region of New South Wales, Australia.
