He is Bing Professor of Population Studies Emeritus and President of the Center for Conservation Biology at Stanford University. Ehrlich is a member of the National Academy of Sciences and a recipient of the Crafoord Prize (an explicit substitute for the Nobel Prize in fields of science where the latter is not given), the Blue Planet Prize, and numerous other international honors. He investigates a wide range of topics in population biology, ecology, evolution, human ecology, and environmental science. Much of his current effort is focused on the mechanisms of human cultural evolution and ways of directing that evolution to ameliorate the human predicament.
