Senior🎓
Top SchoolMark Coletti is a Staff Scientist at Oak Ridge National Laboratory with over a decade of experience advancing evolutionary algorithms and scalable ML workflows on HPC systems. He develops high-performance open-source tools—including the LEAP library and the R&D 100 Award-winning Gremlin—and applies his work to real-world problems like solar plant siting, carbon capture placement, and hyperparameter/architecture search. With a Ph.D. in computer science from George Mason University, he blends deep research on algorithmic dynamics with hands-on CUDA and distributed workflow engineering. His background spans geospatial and multi-agent simulation projects, reflecting a rare combination of evolutionary computation expertise and applied GIS/remote-sensing proficiency. Colletti is notable for translating research-grade algorithms into production-ready HPC software and for organizing collaborative scientific communities, such as a postdoc writing group at ORNL.
