Rollin Thomas is a Senior Computing Engineer in the Programming Environments and Models (PEM) Group at NERSC, and is the Deputy Director of the NERSC-10 Project. Rollin is interested in developing new ways to use high-performance computing for science, including interactive and time-sensitive supercomputing, enabling new user access modes to supercomputing like Jupyter notebooks, and making supercomputing accessible to more scientists through programming languages like Python. In over 20 years at Berkeley Lab, Rollin has worked in the Physics Division, Computational Research Division, and in 2015 joined NERSC. At NERSC, he worked in the Data Analytics Services Group and the Data Science Engagement Group before joining PEM. In recognition of his work at NERSC to bring Jupyter to high-performance computing, Rollin was named a Jupyter Distinguished Contributor in 2023. Rollin has a Ph.D. in Astrophysics from the University of Oklahoma, and a B.S. in Physics from Purdue University.
