About

Ralph Kahn, a Senior Research Scientist at NASA’s Goddard Space Flight Center, received his PhD in applied physics from Harvard University. He spent 20 years as a Research Scientist and Senior Research Scientist at the Jet Propulsion Laboratory, where he studied climate change on Earth and Mars, and also led the Earth & Planetary Atmospheres Research Element. Kahn is Aerosol Scientist for the NASA Earth Observing System's Multi-angle Imaging SpectroRadiometer (MISR) instrument. He focuses on using MISR’s unique observations, combined with other data and numerical models, to learn about wildfire smoke, desert dust, volcano and air pollution particles, and to apply the results to regional and global climate-change questions. Kahn has lectured on Global Climate Change and atmospheric physics at UCLA and Caltech, and is editor and founder of PUMAS, the on-line journal of science and math examples for pre-college education (http://pumas.nasa.gov).
