Joel Cohen
Mathematical Biologist, Rockefeller University
Joel E. Cohen is a mathematical biologist and Professor of Populations at Rockefeller and Columbia Universities. His research deals with the demography, ecology, epidemiology and social organization of human and non-human populations and with mathematical concepts useful in these fields. The author of 14 books, he has been honored with numerous awards, including the Sheps Award from the Population Association of America, the Distinguished Statistical Ecologist Award, the Tyler Prize for Environmental Achievement in 1999 and the Mayor's Award for Excellence in Science and Technology from the Mayor of the City of New York, Michael R. Bloomberg in 2002. Professor Cohen has been elected to the National Academy of Sciences, the American Academy of Arts and Sciences and the American Philosophical Society. He lives in New York.
In his lecture, Professor Joel Cohen teaches you how demography can provide answers to the life or death questions caused by the world’s swelling population and dwindling resources.
