Joel Cohen

Joel E. Cohen is an American mathematical biologist and professor at Rockefeller University and Columbia University. He is known for his work in demography, population science, and food webs, having made significant contributions to understanding population dynamics and human population growth. Cohen's research has focused on the intersection of mathematics, biology, and public policy, with particular emphasis on human population studies and the mathematics of food webs in ecosystems. His book "How Many People Can the Earth Support?" (1995) is considered a definitive work on global population carrying capacity. His academic contributions have earned him numerous honors, including membership in the U.S. National Academy of Sciences and the American Academy of Arts and Sciences. He holds the Abby Rockefeller Mauzé Professorship at Rockefeller University and heads the Laboratory of Populations. Cohen's mathematical models and theoretical frameworks have influenced fields ranging from public health to environmental science. His work continues to inform discussions about global population sustainability, demographic trends, and ecological networks.
