Dr. Druyan is a Senior Research Scientist and the Director of the Center for Climate Systems Research which is a unit of the Earth Institute at Columbia University. Alternatively referred to as "GISS at Columbia", CCSR is the administrative umbrella for many Columbia University research scientists based at the Goddard Institute for Space Studies. D. Druyan's research interests focus on climate variability in tropical latitudes. His published work relates to a range of themes, including the Indian and West African summer monsoons, Sahel drought, African wave disturbances, climate change impacts on tropical cyclones, El Niï¿½o and other sea-surface temperature anomaly impacts on regional climates and seasonal climate prediction for Brazil. He has conducted climate simulation studies using several versions of the GISS GCM and more recently using a regional climate model that represents variables at high spatial resolution over limited areas on a grid with 0.5ï¿½ spacing. Dr. Druyan's research team is studying techniques to downscale GISS GCM climate predictions to a higher spatial resolution using the regional climate model. Dr. Druyan was a contributor to the Encyclopedia of Climate and Weather (Oxford University Press) and he has published many research papers in leading intennational journals of weather and climate over a period spanning some 30 years. He has also served as a referee for submissions to many journals and government agencies.
