Biography:

Dr. Michael E. Mann received his undergraduate degrees in Physics and Applied Math from the University of California at Berkeley, an M.S. degree in Physics from Yale University, and a Ph.D. in Geology & Geophysics from Yale University.

Dr. Mann was a Lead Author on the Observed Climate Variability and Change chapter of the Intergovernmental Panel on Climate Change (IPCC) Third Scientific Assessment Report in 2001 and was organizing committee chair for the National Academy of Sciences Frontiers of Science in 2003. He has received a number of honors and awards including NOAA's outstanding publication award in 2002 and selection by Scientific American as one of the fifty leading visionaries in science and technology in 2002. He shared the Nobel Peace Prize with other IPCC authors in 2007. In 2012 he was inducted as a Fellow of the American Geophysical Union and was awarded the Hans Oeschger Medal of the European Geosciences Union.

Dr. Mann is author of more than 140 peer-reviewed and edited publications, and has published two books: Dire Predictions: Understanding Global Warming in 2008 and The Hockey Stick and the Climate Wars: Dispatches from the Front Lines, due out in early 2012. He is also a co-founder and avid contributor to the award-winning website "RealClimate.org".

Research Interests

Current areas of research include reconstruction of past climate using climate paleoclimate ``proxy'' data, and model/data comparisons aimed at understanding the long-term behavior of the climate system and its relationship with possible external (including anthropogenic) "forcings'' of climate. Other areas of active research include simulation of climate using theoretical models, development of statistical methods for climate signal detection, and investigations of the response of geophysical and ecological systems to climate variability and climate change scenarios.

Teaching Interests

Ocean-Atmospheric Dynamics; Climatology; Paleoclimatology; Statistical and Time Series Methods
