Sebastian is a research scientist at the Massachusetts Institute of Technology's Laboratory for Aviation and the Environment (LAE). His previous work has covered development and application of global atmospheric chemistry and transport models, ranging from his work to implement stratospheric chemistry in the GEOS-Chem community atmospheric model, through to his recent paper discussing the possible health effects of solar geoengineering. He is currently working as a visiting scientist for the Harvard Solar Geoengineering Research Program, investigating the behavior of aircraft plumes in the stratosphere - including those which would be expected to form if stratospheric aerosol injection were ever deployed.

Anthony (Tony) Harding is a postdoctoral fellow researching the intersection of innovative technologies and climate policy. He received his Ph.D. in Economics from Georgia Institute of Technology, where his research focused on climate and energy economics, and earned a BS from Rensselaer Polytechnic Institute in Math and Physics. His research applies both econometrics and economic modelling to evaluate climate policy and climate impacts. Tony’s most recent work estimates the distribution of economic impacts of solar geoengineering across countries and compares it to the impacts of climate change. His current interests include the design of effective international climate governance structures and the measurement of the value of scientific learning.

David 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. David is Professor of Applied Physics at the Harvard School of Engineering and Applied Sciences and Professor of Public Policy at the Harvard Kennedy School, and founder of Carbon Engineering, a company developing technology to capture CO2 from ambient air to make carbon-neutral hydrocarbon fuels....
