Biography

Mohamad Hejazi is a research scientist with the Joint Global Change Research Institute (JGCRI) and the Pacific Northwest National Laboratory. He holds a Ph.D. (2009) from the University of Illinois at Urbana-Champaign, and a B.S. (2002) and M.S. (2004) degrees from the University of Maryland, College Park. His research interests include: global hydrologic modeling, global and regional sectoral water demand models, separating the effect of climate change, human activities, and climate policies on hydrology, and the value of information (e.g. weather and climate forecasts) to human decisions (e.g., farmers, reservoir operators). Prior to joining JGCRI-PNNL, he worked as a postdoctoral research associate at the University of Illinois Urbana-Champaign and as a research assistant at the USGS and the Illinois Water Survey.

Research Interests

  • Modeling water demand and availability in global integrated assessment models;
  • Understanding the water-energy-land-climate interactions;
  • Watershed, regional, and global hydrologic modeling, reservoir operation and optimization, and water scarcity assessment;
  • Climate change impact assessment on water resources, and separating the effect of climate change and human activities on hydrology;
  • Impact of climate change mitigation policies on hydrology;
  • Systems analysis, heuristic optimization techniques, and model calibration
