Gordon McKay Professor of Applied Physics; Professor of Public Policy

David Keith explores the interface between climate science, energy technology, and public policy, with a particular interest in the science and public policy of solar geoengineering.

About David Keith

D. Keith

David Keith is the Gordon McKay Professor of Applied Physics at the Paulson School of Engineering and Applied Sciences and a professor of Public Policy at the Harvard Kennedy School.

Keith has worked near the interface between climate science, energy technology, and public policy for twenty-five years. He took first prize in Canada's national physics prize exam, won MIT's prize for excellence in experimental physics, and was one of TIME magazine's Heroes of the Environment. He is a professor of Applied Physics in Harvard’s School of Engineering and Applied Sciences, a professor of Public Policy in the Harvard Kennedy School, and the founder at Carbon Engineering, a company developing technology to capture of CO2 from ambient air to make carbon-neutral hydrocarbon fuels. Best known for work on the science, technology, and public policy of solar geoengineering, Keith is leading the development of an interfaculty research initiative on solar geoengineering at Harvard. Keith’s work has ranged from the climatic impacts of large-scale wind power to an early critique of the prospects for hydrogen fuel. His hardware engineering projects include the first interferometer for atoms, a high-accuracy infrared spectrometer for NASA's ER-2, and currently, development of CO2 capture pilot plants for Carbon Engineering. Keith teaches courses on Science and Technology Policy and on Energy and Environmental Systems where he has reached students worldwide with an online edX course. He has written for the public with A Case for Climate Engineering from MIT Press. Based in Cambridge, Keith spends about a third of his time in Canmore, Alberta.
