Summary
👤
Senior🎓
Top SchoolRobert Harrison is a professor and director of the Institute for Advanced Computational Science at Stony Brook University with 32 years of experience leading large-scale computational science initiatives across national labs and academia. Trained with a PhD in theoretical chemistry from Cambridge, he has directed centers at Oak Ridge and Brookhaven National Laboratories and served as Chief Scientist for computational science, bridging domain science with high-performance computing infrastructure. He is a hands-on contributor to high-performance open-source projects such as NWChem, where his Fortran work improved core algorithms and performance for computational chemistry at scale. Known for building interdisciplinary programs that translate advanced computing into economic and research impact for New York State, he combines deep technical expertise with strategic institutional leadership. An often-overlooked strength is his sustained ability to move between low-level code optimization and high-level program building, enabling both scientific advances and operational delivery.
