  1. PhD -- Massachusetts Institute of Technology

Research Specialties:



Dr. Forest joined the faculty in the Department of Meteorology at The Pennsylvania State University in 2008 after 12 years as a Research Scientist at MIT working in the Joint Program on the Science and Policy of Global Change. He served as a Lead Author on the Climate Change Science Program SAP1.1 Report examining the estimates of temperature trends in the atmospheric and surface climate data and contributed to the IPCC AR4 Working Group 1 Chapter 11. He was an IPCC AR5 Lead Author on Chapter 9, "Evaluation of Climate Models" in Working Group 1. Dr. Forest was elected to serve on the Electorate Nominating Committee (ENC) through February 2018 for the Atmospheric and Hydrospheric Sciences Section of the American Association for the Advancement of Science (AAAS). Dr. Forest graduated from the University of Wisconsin-Madison in 1990 with a BS in Applied Math, Engineering, and Physics and from the Massachusetts Institute of Technology in 1996 with a PhD in Meteorology (thesis advisors: Kerry A. Emanuel and Peter Molnar).
