Dr. Marilyn Raphael is the director of the UCLA Institute of the Environment and Sustainability, Professor of Geography at UCLA, and served as Department Chair from 2010-2013. Her primary research focus is Southern Hemisphere (SH) atmospheric dynamics and climate change and her major scientific goals are to characterize the Antarctic sea ice variability and to define and understand the interaction between Antarctic sea ice and the large-scale Southern Hemisphere circulation, focusing on interaction at the seasonal, interannual and decadal time scales. Her work includes global climate modeling with an emphasis on improving the simulation of sea ice and the atmosphere in the Southern Hemisphere.

She is a member of the American Academy of Arts and Sciences, current Chair of the Scientific Committee on Antarctic Research’s expert group, Antarctic Sea ice Processes and Climate (ASPeCt) and Co-Chair of the World Climate Research Programme’s (WCRP) Polar Climate Predictability Initiative (PCPI). She has served on the National Research Council’s Committees on Future Science Opportunities in Antarctica and the Southern Ocean and Stabilization Targets for Atmospheric Greenhouse Gas Concentrations.
