His research focuses on the interaction of energy systems, technological change, and climate policy. His most influential work examines how solar and carbon geoengineering technologies affect climate policy. His most recent work provides novel insights into the process of energy transitions by demonstrating how energy access shapes the organization of the economy in cities and how energy consumption in cities in turn pollutes the local and global environment.
His publications have appeared in the Journal of Environmental Economics and Management, Journal of Economic Behavior and Organization, Energy and Resource Economics, Resources and Energy Economics, as well as in interdisciplinary journals such as the Proceedings of the National Academy of Sciences, Nature Geosciences, Science, Economic Policy, Climatic Change Journal, Environmental Research Letter and Ecological Indicators.
