Marilyn Brown is a Regents' and Brook Byers Professor of Sustainable Systems in the School of Public Policy. She joined Georgia Tech in 2006 after a distinguished career at the U.S. Department of Energy's Oak Ridge National Laboratory, where she led several national climate change mitigation studies and became a leader in the analysis and interpretation of energy futures in the United States. 

Her research focuses on the design and impact of policies aimed at accelerating the development and deployment of sustainable energy technologies, with an emphasis on the electric utility industry, the integration of energy efficiency, demand response, and solar resources, and ways of improving resiliency to disruptions. Her books include Fact and Fiction in Global Energy Policy (Johns Hopkins University Press, 2016), Green Savings: How Policies and Markets Drive Energy Efficiency (Praeger, 2015), and Climate Change and Global Energy Security (MIT Press, 2011). She has authored more than 250 publications. Her work has had significant visibility in the policy arena as evidenced by her numerous briefings and testimonies before state legislative bodies and Committees of both the U.S. House of Representatives and Senate.

Dr. Brown co-founded the Southeast Energy Efficiency Alliance and chaired its Board of Directors for several years. She has served on the Boards of the American Council for an Energy-Efficient Economy and the Alliance to Save Energy, and was a commissioner with the Bipartisan Policy Center. She has served on eight National Academies committees and is an Editor of Energy Policy and an Editorial Board member of Energy Efficiency and Energy Research and Social Science. She served two terms (2010-2017) as a Presidential appointee and regulator on the Board of Directors of the Tennessee Valley Authority, the nation’s largest public power provider. From 2014-2018 she served on DOE’s Electricity Advisory Committee, where she led the Smart Grid Subcommittee.

Tim Lieuwen is the executive vice president for research (EVPR) at the Georgia Institute of Technology. In this role, he oversees the Institute’s $1.4+ billion portfolio of research, economic development, and sponsored activities. This includes leadership of the Georgia Tech Research Institute (GTRI), the Enterprise Innovation Institute, 11 interdisciplinary research institutes (IRIs), and related research administrative support units.

In his 25-plus years at Georgia Tech, Lieuwen earned his master's and Ph.D. degrees in mechanical engineering (1996 and 1999, respectively) and has held multiple leadership positions. He has been the executive director of the Strategic Energy Institute (SEI) and served as the interim chair of the Daniel Guggenheim School of Aerospace Engineering in 2023.

Lieuwen has received numerous honors and recognition for his work in clean energy systems and policy, national security, and regional economic development. Additionally, he has been awarded the titles of Regents’ Professor and the David S. Lewis, Jr. Chair in AE. He is also a member of the National Academy of Engineering and is a fellow of the American Society of Mechanical Engineers and the American Institute of Aeronautics and Astronautics.

The Strategic Energy Institute is excited to welcome Scott McWhorter as a 2023 Distinguished External Fellow. Scott will co-lead the concept development, visioning, partnership, and preliminary capture activities for Georgia Tech on the Department of Commerce Tech Hubs (“Hubs”) and expand Georgia Tech’s hydrogen activities and stature.

Scott is not new to the Georgia Tech campus and has previously worked with Dan Campbell of the Georgia Tech Research Institute (GTRI) on developing trace organic optical sensors based on evanescent waveguides. More recently, Scott worked with David Sholl (professor in the School of Chemical and Biomolecular Engineering at Georgia Tech through 2021), to develop the RAPID (Rapid Advancement in Process Intensification Deployment) Institute and then through his work with Southeast Hydrogen Energy Alliance (SHEA), started working with Comas Haynes of GTRI on hydrogen, where they brought together the ecosystem that was responsible for at least three hydrogen hub efforts in the South East.

Scott's work related to energy in his own words: 
My career has always related to energy even when I didn’t notice it. I started out in DNA microchips where we tried to understand the various aspects of fluidics (mass transport, thermal, and surface science) that influenced efficient separations. Using the tools from those efforts I transitioned into optical sensor development to monitor trace gases from the gas-solid catalyst interface in a fuel cell electrode to an unknown-unknown contaminant that might cause a failure mode in a weapons system. Over the past decade, my work in energy has focused namely on building partnerships in industrial manufacturing consortia (ManufacturingUSA Institutes) where I helped form both CESMII and RAPID and then focusing on developing technologies to solve the hydrogen storage and delivery challenges through either more efficient, energy dense solid-state storage or using electro magnetics to efficiently provide heat to catalysts to decompose a hydrogen carrier or plastic.

Marta Hatzell is a professor of mechanical engineering at Georgia Institute of Technology. Prior to starting at Georgia Tech in August of 2015, she was a post-doctoral researcher in the Department of Material Science and Engineering at the University of Illinois - Urbana-Champaign. During her post doc, she worked in the Braun Research Group on research at the interface between colloid science and electrochemistry. She completed her Ph.D. at Penn state University in the Logan Research Group. Her Ph.D. explored environmental technology for energy generation and water treatment. During graduate school she was an NSF and PEO Graduate Research Fellow. 

Currently her research group focuses on exploring the sustainable catalysis and separations, with applications spanning from solar energy conversion to desalination. She is an active member of the American Chemical Society, the Electrochemical Society, ASEEP, and ASME. Hatzell was awarded the NSF Early CAREER award in 2019 for her work on distributed solar-fertilizers, attended the 2019 US Frontiers of Engineering Symposium through the National Academy of Engineering, and was awarded the 2020 Sloan Research Fellowships in Chemistry.
