Jesse Kroll is the Peter de Florez Professor at MIT’s Departments of Civil and Environmental Engineering and Chemical Engineering, and a Faculty Director of MIT’s Climate Project. He received his Ph.D. in Chemistry from Harvard University in 2003, and was a postdoc at Caltech and a Research Scientist at Aerodyne Research, Inc., before joining the MIT faculty in 2009. His group carries out research on atmospheric oxidation processes, with a focus on the formation of oxidized organic compounds and secondary organic aerosol, the development of simplified descriptions of complex atmospheric mechanisms, and the use of lower-cost sensors for characterizing atmospheric composition and chemistry.

Arlene Fiore joined the faculty at MIT in 2021 as the Peter H. Stone and Paola Malanotte Stone Professor of Earth, Atmospheric and Planetary Sciences. She attended Harvard University, earning an AB in environmental geoscience in 1997 and completing her PhD studies in Earth and planetary sciences in 2003. Fiore spent seven years as a research scientist at the NOAA Geophysical Fluid Dynamics Laboratory before being appointed to the faculty at Columbia University’s Department of Earth and Environmental Sciences and Lamont-Doherty Earth Observatory in 2011. Her research seeks to understand processes that control two-way interactions between air pollutants and the climate including linkages with global atmospheric composition and the terrestrial biosphere. Her group also investigates drivers of atmospheric oxidizing capacity and applies satellite datasets to address emerging needs of air quality and public health groups.
