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.

Ching-Hua Huang, Ph.D., is the Turnipseed Family Chair and Professor in the School of Civil and Environmental Engineering at Georgia Institute of Technology. Huang received her Ph.D. and M.S. degrees in environmental engineering from Johns Hopkins University. Huang’s expertise includes environmental chemistry, advanced water/wastewater treatment technology, contaminants of emerging concern, sustainable water reuse, waste remediation and resource recovery. Huang has supervised many research projects sponsored by various agencies, and has published more than 170 peer-reviewed journal papers, book chapters and conference proceeding papers. She is the Associate Editor of the American Chemical Society's Environmental Science & Technology Water and the Editorial Advisory Board member of Environmental Science & Technology. 

Thomas DiChristina, Ph.D., received a BS in Chemical Engineering from the University of Rochester (NY) in 1982, a MS in Chemistry from the University of Bordeaux (France) in 1984, a Ph.D. in Environmental Engineering Science from the California Institute of Technology (CA) in 1989, and a Postdoctoral Fellowship from the Woods Hole Oceanographic Institution (MA) in 1993. DiChristina has been at Professor of Microbiology in the School of Biological Sciences at Georgia Tech for 29 years. 

Johannes Milz is an Assistant Professor in the H. Milton Stewart School of Industrial and Systems Engineering. His research focuses on optimization under uncertainty and optimal control of uncertain systems, with a strong emphasis on sustainability applications. By addressing large-scale optimization challenges in physics-based models under uncertainty, he aims to contribute to the development of sustainable energy systems, such as renewable tidal energy farms. Dr. Milz is also dedicated to open science; he develops reproducible numerical simulations and shares them publicly, making his results accessible to a broad group of researchers and practitioners. Prior to joining ISyE, he was a postdoctoral researcher at the Technical University of Munich, where he earned his Ph.D. in Applied Mathematics in 2021.
