Ganesh R Ghimire

Research and Development Staff

Dr. Ganesh Ghimire is an R&D Staff 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 ML/DL applications in surface hydrology. He is one of the creators of the CONUS-scale streamflow reanalysis (Dayflow)DayflowV2CONUS-scale multi-model streamflow projections, and Hydropower Energy Storage Capacity (HESC) datasets and corresponding updates. He is a PI and co-PI on multiple ORNL-led research projects funded by DOE and DOD. 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 received the Dan Branson Fellowship from the Department of Civil and Environmental Engineering, UIowa in 2021. He is also actively involved in water resources research in the Central Himalayan Region through Water Resource Group Nepal. Dr. Ghimire has frequently reviewed more than ten high-impact scientific/engineering journals and has been active in leading scientific sessions at AGU and AMS annual meetings, and many outreach activities over the past several years.
