Biography

Jean-François is a Senior Scientist at the National Center for Atmospheric Research. He is the current Climate and Global Dynamics (CGD) Laboratory Director. Until early 2018, he was Community Earth System Model (CESM) Chief Scientist. He was a Lead Author on Chapter 8 (Radiative forcing) of IPCC AR5, published in 2013. He is the author or co-author of over 250 papers. He received his Ph.D. from the Catholic University of Louvain (Belgium) in 1993, with Pr. Berger and Dr. Brasseur as joint advisors. He was an ASP postdoc from 1993-1995. He has worked at NCAR since then, except for a one-year leave of absence to join the NOAA Chemical Science Division (2008-2009).

His research focuses on the use of models to understand the long-term changes of short-lived climate forcers (i.e. ozone, aerosols, and methane). He has published several papers focusing on the transient behavior of tropospheric chemistry since the mid-nineteenth century. In particular, he has made use of ice-core measurements of black carbon and sulfate aerosols to validate model simulations of those compounds. Other applications include the modeling of paleo-atmospheres under massive chemical perturbations.
