Summary
🤩
Rockstar🎓
Top SchoolJibonananda Sanyal is a multidisciplinary energy systems and computational sciences leader with 12 years of experience translating HPC, AI, and simulation research into large-scale energy and urban technology deployments. As Group Manager III for Hybrid Energy Systems and Acting GM for Thermal Energy Science and Technology, he directs multimillion-dollar R&D programs and a $200M emulation platform (ARIES) that spans kW-to-MW hardware-in-the-loop, digital twins, and grid-ready validation. He previously founded and grew ORNL’s Computational Urban Sciences group, delivering city-scale digital twins, real-time situational awareness for national energy infrastructure, and measurable mobility energy savings through edge AI and control. A hands-on technologist with a PhD in computer science, he has contributed backend improvements to the widely used EnergyPlus simulation codebase—adding JSON time-series outputs to improve interoperability and analytics. His work uniquely bridges deep software craftsmanship, large-scale HPC experiments, and practical commercialization (including startup CTO experience and filed patents), focused on scaling energy technologies to tens of megawatts across geography and time. Based in Oak Ridge, TN, he combines academic rigor with operational leadership to de-risk complex energy system transitions.
