Sarat Sreepathi is a Computer Scientist interested in interdisciplinary research at the intersection of High Performance Computing and domain sciences. As Performance Coordinator for the Energy Exascale Earth System Model (E3SM) project (DOE’s flagship climate modeling effort), he led an interdisciplinary team of scientists across the national lab complex to focus on computational performance and application readiness on exascale supercomputers. His team won the inaugural ACM Gordon Bell Prize for Climate Modeling.

He is the High Performace Computing Lead in the Working Group on Numerical Experimentation (WGNE) within World Climate Research Programme (WCRP).
He served on the SciDAC (Scientific Discovery through Advanced Computing) Coordination Committee, , Interagency Council on Advancing Meteorological Services (ICAMS) High Performance Computing (HPC) implementation team, NERSC (National Energy Research Scientific Computing Center) User Group Executive Committee and as Chair of the OLCF (Oak Ridge Leadership Computing Facility) User Group Executive Board (2020-2021).

He was a member of the Future Technologies Group (2013-2020) and the Computational Earth Sciences Group (2021 - 2025) in the Computing and Computational Sciences Directorate at Oak Ridge National Laboratory. He is a Senior member of ACM and IEEE. He received his Ph.D. in Computer Science from North Carolina State University.

He led application co-design efforts as a member of the Exascale Computing Project (ECP) for climate and fusion workloads. He is the Computational Readiness Lead and Co-PI for Innovative and Novel Computational Impact on Theory and Experiment (INCITE) supercomputer allocations for XGC (fusion) and E3SM projects respectively.

His research interests include High Performance Computing, Computational Climate Science, Performance Analytics, Exascale Co-design, Optimization Algorithms, Computational Intelligence, Parallel I/O, Performance Analysis and Optimization and has modeling experience in Water Distribution Systems, Groundwater/Subsurface and Energy Economy Optimization.
