The Energy Systems Analysis Group (ESAG) includes core members plus visiting researchers and students, in addition to collaborators worldwide. ESAG’s alumni (former students and postdoctoral fellows) work in industry, government, academia, and non-governmental organizations.
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 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., China, and elsewhere. A recent research emphasis has been design and analysis of advanced biomass and fossil fuel conversion to clean transportation fuels and electricity with CO2 capture and storage. Larson 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.
Joe Lane, Associate Research Scholar (Lane full CV)
Joe’s research builds on his past experiences in industrial engineering and government management of natural resources, through which he developed an interest in the integration of complex environmental and socio-economic trade-offs into decision making. This led to a cross-disciplinary PhD (2015) on life-cycle perspectives for the urban water industry using a variety of methodologies to analyze barriers and opportunities for major change to water, food and energy systems. Joe’s current research aims at improving our understanding of how to accelerate decarbonization of energy systems. His research has a twin focus: (i) identifying and communicating major risks to achieving rapid and deep decarbonization globally, and (ii) developing a systematic understanding of the medium-long term bottlenecks that might constrain efforts to decarbonize the rapidly growing Indian energy sector.
Ali Daraeepour, Postdoctoral Research Associate (Daraeepour full CV)
Ali uses systems analysis, economics, optimization, and engineering to provide quantitative answers to important policy questions in the electricity sector. His research focuses on market design and grid operation reforms to enhance economic and environmental efficiency of electricity grids with continued growth in variable renewable electricity and emerging technologies that support advancing zero-emission objectives. His PhD dissertation (2017, Duke University) addressed understanding grid-integration of variable renewable resources and related design of electricity markets and processes underlying operation of electricity grids. Prior to his PhD, he worked for several years as a power system engineer and consultant. Ali is a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE), the world’s largest professional association dedicated to advancing technological innovation.
Andrew Pascale, Postdoctoral Research Associate (Pascale full CV)
Andrew’s interests are in timely low carbon energy transitions that allow inclusive high development levels for all global populations, while remaining within safe planetary boundaries. In 2018, Andrew both led the technical design and installation of a 3.4 kW solar PV system powering a sewing workshop in a remote village in rural Thailand and was awarded a PhD from the University of Queensland, Australia. His PhD dissertation refines standard presentations of energy use/carbon dioxide emissions and human welfare relationships to expose intra-country inequalities and allow compelling global challenges connected with the vision of a world characterized by universal High human development and minimal global warming to be framed for individuals rather than nations.
Erin Mayfield, Postdoctoral Research Associate (Mayfield CV)
Erin is an environmental engineer and public policy researcher, with expertise in complex systems analysis, optimization, and environmental economics. In 2019, she completed her Ph.D. in Engineering and Public Policy at Carnegie Mellon University, researching the air quality, climate, and labor market impacts and equity implications of energy-system transitions. She previously worked as an environmental consultant on natural resource damages litigation and ecosystem service modeling, and has held positions at the U.S. Environmental Protection Agency, U.S. Congress, and Environmental Law Institute. She received her bachelor’s degree in environmental science from Rutgers University and master’s degree in environmental engineering from Johns Hopkins University.
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.
