David Keith is a Professor in the Department of Geophysical Sciences at the University of Chicago and the Founding Faculty Director of the Climate Systems Engineering initiative.

Keith previously served as the Gordon McKay Professor of Applied Physics at the Harvard University School of Engineering and Applied Sciences and as Professor of Public Policy at the Harvard Kennedy School. He led the development of Harvard’s Solar Geoengineering Research Program.

His work has ranged from the climatic impacts of large-scale wind power to elicitation of expert judgments about climate. Keith’s hardware engineering projects include the first interferometer for atoms, a high-accuracy infrared spectrometer for NASA’s ER-2 and the development of a stratospheric propelled balloon experiment for solar geoengineering. He is also the founder of Carbon Engineering, a company developing technology to capture CO2 from ambient air and the author of A Case for Climate Engineering (MIT Press, 2013).
