Paul R. Ehrlich received his Ph.D. from the University of Kansas. He has been a pioneer in alerting the public to the problems of overpopulation and in raising issues of population, resources and the environment as matters of public policy. Professor Ehrlich's research group covers several areas and continues to study the dynamics and genetics of natural populations of checkerspot butterflies (Euphydryas). This research has applications to such problems as the control of insect pests and optimum designs for nature reserves.

Professor Ehrlich has received several honorary degrees, the John Muir Award of the Sierra Club, the Gold Medal Award of the World Wildlife Fund International, a MacArthur Prize Fellowship and many others. Members of Professor Ehrlich’s research group have gone on to join the faculties of Princeton, Brown, and the Universities of California, Nevada, Texas and Florida.
