Dr. Voisin is staff water resources engineer at the Pacific Northwest National Laboratory where she leads inter-disciplinary research on regional water-energy dynamics for the Department of Energy. She holds a dual appointment as assistant professor in Civil and Environmental Engineering at the University of Washington. Her expertise lies in coupling climate, hydrology and water resources management models with power system models including production cost and aggregated building energy demand models. Most recent efforts led to a better understanding of drought and heat wave patterns that are most challenging for grid operations, quantified predictability of grid operations economics associated with climate phases, projections of hydropower that include the representation of environmental and power system regulation, a risk-based implementation of future water availability and climate-driven load disturbances into resources adequacy studies. Dr. Voisin holds a bachelor degree in Fluid Mechanics and Hydraulics Engineering from ENSEEIHT, France, a M.Sc. in Atmospheric Sciences from McGill University, Canada and a Ph.D. in Water Resources Engineering from the University of Washington, USA.

Nathalie Voisin has led research involving the following capabilities:

  • Hydrology Model: CLM (Fortran), VIC (C), DHSVM (C)
  • Water management model: MOSART-WM (Fortran), RiverWare, ColSim (Stella)
  • Power system models: PROMOD, PLEXOS, GENESYS, GCAM, Aurora, RPM
