Seb is a principal research scientist at the Joint Program on the Science and Policy of Global Change and the Center for Global Change Science. His research career began at Cambridge, where he worked on the environmental impact of expanding Heathrow Airport as part of his undergraduate degree. Seb completed a PhD in Aeronautical Engineering at MIT in 2015, followed by a two year postdoctoral fellowship at Harvard in the Atmospheric Chemistry Modeling Group, supported jointly by the Harvard University Center for the Environment and by the National Oceanic and Atmospheric Administration’s Climate and Global Change program. He joined the Laboratory for Aviation and the Environment as a research scientist in 2017, before moving to the Center for Global Change Science in 2022.
Seb’s work is focused on understanding and reducing the atmospheric impacts of anthropogenic emissions using high-resolution computational models of the atmosphere in concert with Earth observations. This ranges from high-fidelity local simulations of single exhaust plumes up to global-scale numerical models of the atmosphere. His research also benefits from the application of machine learning methods to Earth observation data, such as ongoing work to identify and characterize aircraft condensation trails – and from there quantify their climate impacts – in geostationary satellite imagery. The long-term goal of his work is to enable near real-time integration of observational (monitor, aircraft, and satellite) data into computational models of the environment, supporting unprecedented accuracy and insights with regards to environmental decision making for impact mitigation and environmental justice.
