Ralph Kahn

Ralph A. Kahn

Ralph A. Kahn received his Ph.D. in applied physics from Harvard University in 1980, concentrating in atmospheric physics and radiative transfer. His research interests include the climate and climate history of Mars, Venus, and Earth. A primary theme of his work has been to analyze global-scale data sets, bringing to bear theoretical models and other observations as needed. He was an experimenter on the Viking Lander Imaging team, and was responsible for imaging the sunset of Mars. He has been a Research Scientist at the Jet Propulsion Laboratory since 1988, where he works primarily on Earth observations. He is a member of the MISR science team, specializing in tropospheric aerosol research. Dr. Kahn has lectured on global change and atmospheric physics at UCLA, the Claremont Colleges, and Caltech, and is editor and founder of PUMAS, the on-line journal of science and math examples for pre-college education (http://pumas.jpl.nasa.gov).
