In 1972, she moved to Yale University where she taught and continued her research on the ecology and social behavior of wild primates in Central America, West Africa, the Himalayan foothills of Pakistan, and the southern forests of Madagascar. She was named Professor of Anthropology in 1986 and chaired the Department of Anthropology at Yale from 1986 to 1990. From 1991 to 1994 she was the Director of Yale's Peabody Museum of Natural History, which houses one of the world’s most important university natural history collections. In 1998 she was named the Franklin Muzzy Crosby Professor of the Human Environment. Richard is best known for her studies of the sifaka, a lemur of southern and western Madagascar. With collaborators and students, she led a program of field observation, capture and release, anatomical measurement, and genetic and hormone sampling, of more than 700 individually known sifaka from 1984 to the present. This is one of the largest primate populations continuously observed for such a long period. The research has yielded valuable insights into sifaka life-histories, demography, social behavior, and genetics. These, in turn, expand the understanding of the variation in the lives and biology of the members of the primate order.
University administration
From 1994 until 2002, she was Provost of Yale University with operational responsibility for the University’s financial and academic programs and planning. From 2003 to 2010, Richard was the Vice-Chancellor of the University of Cambridge. During her tenure, she led several major changes in university policy, ranging from intellectual property to undergraduate financial aid, re-organized management of the University's endowment, and expanded Cambridge’s global partnerships, most notably in the US, China, India, Singapore, and the Persian Gulf. She launched and completed a billion-pound fund-raising campaign, the largest ever for a UK university.
Conservation
In the 1970s, in collaboration with RW Sussman and G Ramanantsoa, she helped establish a nature reserve at Beza-Mahafaly, southwest Madagascar, which was formally incorporated into the Madagascar Nature Reserve system in 1986. For more than three decades, she has worked with colleagues to help conserve the reserve’s unique natural heritage, sponsor training and research by students from Madagascar and elsewhere, and to enhance socio-economic opportunities for people living in and around the forest. Over the years, these conservation efforts have been funded by the Liz Claiborne Art Ortenberg Foundation, WWF, the Schwartz Foundation, and USAID.
Advisory boards
Richard is currently a member of the Boards of the Howard Hughes Medical Institute, and of WWF International. She serves as an advisor to the Liz Claiborne/Art Ortenberg Foundation, Arcadia Fund, and to the Cambridge Conservation Initiative. She is also Chairman of the Advisory Board of the executive search firm Perrett Laver.
