Professor Chris O'Dell received his Ph.D. studying the Cosmic Microwave Background radiation. It led to the tightest upper limit on the polarization of the CMB at that time. Because of concerns about anthropogenically-forced changes in the earth's climate, Chris took a post-doc position in the Department of Atmospheric and Oceanic Sciences at the University of Wisconsin-Madison, where he spent three years researching satellite-based measurements of clouds, water vapor, and carbon dioxide. He then did a brief internship at the European Centre for Medium-Range Weather Forecasts (ECMWF) in Reading, UK, on the assimilation of cloud- and precipitation-affected microwave radiances into the ECMWF forecast model. After this, Chris moved to Colorado State University, to work primarily on building a retrieval of carbon dioxide from newly-available near-infrared satellite measurements. Chris joined the faculty of the CSU Department of Atmospheric Science in August 2012.
