Eric D. Larson, Senior Research Engineer, Group Head (Larson full CV)
Larson’s research intersects engineering, environmental science, economics, and public policy. His energy systems modeling and analyses aim at identifying sustainable, engineering-based solutions to major energy-related problems. His work assesses resource, economic, and environmental implications of prospective technology developments and helps inform public and private decision making in the U.S. and elsewhere. He has published extensively on the design and analysis of advanced biomass and fossil fuel conversion technologies with CO2 capture and storage. He was part of the Princeton team contributing to the National Research Council report, America’s Energy Future: Technology and Transformation (2009). He was a Co-Convening Lead Author of the fossil energy chapter of the major international study, The Global Energy Assessment (2012). He co-leads Princeton’s ongoing Net-Zero America project, and he is active in the global Rapid Switch initiative established by the Andlinger Center. Larson is an Affiliated Faculty member with the High Meadows Environmental Institute and the Center for Policy Research on Energy and Environment in the School of Public and International Affairs at Princeton. He also holds an appointment as a senior scientist with Climate Central, a non-profit, non-partisan science and media organization that informs diverse audiences about climate change and potential solutions.
Chris Greig, Theodora D. ’78 & William H. Walton III ’74 Senior Research Scientist (Greig full CV)
Chris commenced a 25-year career in industry in 1986 as the co-founder of a successful process technology and contracting company, which he sold in 1999 to a major European engineering company. From 1999 to 2011, he held senior project and executive roles in the construction and energy resources sectors, including as CEO of ZeroGen, a large-scale carbon capture and storage (CCS) project. In 2011 he joined the faculty of the University of Queensland (Australia), where he led both the UQ Energy Initiative and the Dow Centre for Sustainable Engineering Innovation. He also served as Chairman of the Energy Policy Institute of Australia, Deputy Chairman of Gladstone Ports Corporation, and Non-Executive Director of two ASX listed engineering companies. He was a Gerhard R. Andlinger Visiting Fellow in Energy and Environment at the Andlinger Center from 2018 to 2020, and joined Princeton University as a Senior Research Scientist in August 2020. He also holds an Adjunct Professorship at UQ. Chris has a PhD in chemical engineering from UQ and is a Fellow of the Australian Academy of Technological Sciences and Engineering. His research interests lie in energy transitions, economics and policy, energy for development, mega-project implementation, and CO2 capture and storage systems.
Chuan Zhang, Postdoctoral Research Associate (Zhang CV)
Chuan’s research interests center on technological energy transitions and sit at the intersection between system modeling, environmental assessment and economics analysis. He completed his PhD in 2019 within a joint program of Nanyang Technological University (Singapore) and Cambridge University (UK). His dissertation focused on optimal design and operation of energy systems at various temporal and spatial scales using techno-economic-environmental modeling and mathematical programing. His interests include techno-economic evaluation of energy-sector decarbonization technologies, including decarbonized fossil fuel power generation. Chuan also has interests in understanding potential impacts of advances in artificial intelligence on energy-system transitions.
Loïc De Weerdt, Postdoctoral Research Associate (De Weerdt CV)
Loïc’s research interests include the transition towards a carbon-neutral circular economy, techno-economic evaluations of green microgrids, investments under various types of uncertainty, social welfare maximization, waste management, and sustainable development. He has a PhD in Applied Economics from the University of Antwerp (Belgium) and undergraduate degrees in environmental economics and in European Union law. For his PhD dissertation, he analyzed the market acceptance of circular plastics in Europe. Previously, he was also a member of the Flemish Circular Economy Policy Research Center, a hub of researchers that focus on policy-oriented research questions.
