According to Wikipedia, Carolus Philippus "Carel" van Schaik is a Dutch primatologist who since 2004 is professor and director of the Anthropological Institute and Museum at the University of Zürich, Switzerland. Van Schaik studied biology at the University of Utrecht, graduating in 1979. He was a researcher for the Netherlands Foundation for the Advancement of Tropical Research until 1984 and finished his doctoral dissertation for the Utrecht University in 1985. After positions at this university and at Princeton University, he became Associate Professor at the Department of Biological Anthropology and Anatomy at Duke University in Durham in 1989. In 2004 he moved to the University of Zurich. In 2007 Van Schaik became a correspondent of the Royal Netherlands Academy of Arts and Sciences.
