Prior to joining UC Berkeley, she was an Assistant Professor of Economics and Public Policy at the University of Michigan. She received a MSc in Environmental Economics from Cornell University in 2000 and PhD in Environmental and Resource Economics from UC Berkeley in 2006. Her interests lie at the intersection of empirical industrial organization, environmental economics, and public policy. Much of her work involves positive, and some normative, analysis of policy interventions designed to reduce the environmental impacts of energy production and consumption. Her work on the electricity sector has emphasized interactions between electricity markets and emissions permit markets. She is a Faculty Research Fellow at the National Bureau of Economic Research in the Environmental and Energy Economics group.
