Dr. Reed's primary research interests relate to sustainable water management given conflicting demands from renewable energy systems, ecosystem services, expanding populations, and climate change. The tools developed in Dr. Reed's group bridge sustainability science, risk management, economics, multiobjective decision making, operations research, computer science, and high performance computing. Engineering design and decision support software developed by Dr. Reed has been used broadly in governmental and industrial application areas (e.g., civil infrastructure planning and management, airline logistics, and US satellite constellation design and management). His open source and free academic software related to multiobjective optimization has thousands of users across the world.
