Bio
Dr. Ganesh Ghimire is an R&D Scientist in the Water Resource Science and Engineering Group of the Environmental Sciences Division at Oak Ridge National Laboratory (ORNL). His research at ORNL spans a broad range of water resources, including large-scale hydrologic modeling, flood simulation, streamflow (flood) forecasting, high-performance computing, extreme event analysis, uncertainty assessments, hydroclimate impact assessment, water-energy nexus, and AI/ML applications in hydrology. He is one of the lead creators of the CONUS-wide Streamflow Reanalysis (Dayflow), CONUS-wide Ensemble Streamflow Projections, Hydropower Energy Storage Capacity (HESC), CONUS-wide Projected Flood Frequency, and Dayflow-PR datasets. He is part of the development team for GPU-enabled 2D flood inundation model, TRITON. He is a PI and co-PI on multiple ORNL-led research projects funded by DOE, DOD, and other state and federal agencies. Beyond current efforts, Dr. Ghimire has research interests in remote sensing, data assimilation, and natural hazards. His Ph.D. dissertation on “Streamflow Predictability Across Space and Time Scales” was awarded the prestigious Ballard and Seashore Ph.D. dissertation fellowship by the University of Iowa (UIowa) in 2020. He is also actively involved in water resources research in the Central Himalayan Region through Water Research Group Nepal. Dr. Ghimire serves as an Associate Editor of Journal of Hydrology. He frequently reviews for several high-impact scientific journals in the field and has been active in leading scientific sessions at AGU and AMS annual meetings, and many scientific outreach activities over the past several years.
