Biography

Gerad Freeman joined Pacific Northwest National Laboratory in 2020, where he is an energy systems engineer in the Distributed Systems group. He is a member of the System Planning team, a group of multi-disciplinary researchers focusing on complex, multi-domain analyses that center on how technology change affects energy systems, people, and the environment. Freeman’s current research focuses on intersections between critical infrastructure interdependencies, organizational decision-making, and decarbonization policy objectives. To execute his research scope, Freeman’s teams often develop modeling, software, and numerical frameworks to join sponsors’ collected data with multiple-criteria decision analysis methods to prioritize capital expenditures and staffing to meet sponsors’ mission and vision requirements.

Before joining PNNL, Freeman worked as an engineering project manager in the natural gas distribution industry. During his gas utility work, he oversaw projects to expand natural gas infrastructure to supply the energy needs of large end-users in the commercial, industrial, and governmental sectors. He provided energy efficiency, process improvement, and sustainable energy use consultation services to his clients.

Freeman has earned a PhD and MS in engineering and public policy from Carnegie Mellon University, an MS in alternative energy from the University of Rochester, and a BS in energy, business, and finance from The Pennsylvania State University.
