An Emeritus Fellow, Emeritus Professor of Development Studies and Fellow of the Academy of Social Sciences, Barbara Harriss-White’s research persists into retirement. A political economist and field-economist, Harriss-White studies the social ordering and state regulation of the market economy (through five decades of field research on basic commodities in various regions of South Asia and through four decades of field-research on the development of a small market town and its rural hinterland). She also studies the casualties  of development (hence field research into gender discrimination, poverty, destitution, malnutrition/alcoholism, disability, social discrimination, ageing, incomplete citizenship, and the social contamination of waste). Since 2011, Harriss-White is finding out about the economy as a waste-producing system and the criminal extraction of natural resources. She supervised 40 doctoral students.

Harriss-White was a director of Oxford's Department of International Development, Queen Elizabeth House, first director of the M. Phil. in Development Studies (1996+), founder-director of the Contemporary South Asian Studies Programme in the School of Area Studies and its MSc in Contemporary India (2008), founder-coordinator of Wolfson’s South Asia Research Cluster and member of Wolfson’s Earth Emergency Research Cluster.

Professor Timothy Key took a DPhil in cancer epidemiology at Wolfson in 1988. His main interests are the roles of diet and hormones in the aetiology of cancer, and the health status of vegetarians and vegans.  Key's  research has clarified the importance of oestrogen in the aetiology of breast cancer and the role of insulin-like growth factors in the development of both breast and prostate cancer.  His research group has also shown that vegetarians have a lower risk of heart disease than meat-eaters. 

Mostly Key works on the European Prospective Investigation into Cancer and Nutrition (EPIC), as the principal investigator of the Oxford cohort of 60,000 subjects, including 30,000 people who don’t eat meat.  Key is also chairman of the EPIC prostate cancer group; he co-ordinates the international Endogenous Hormones and Breast Cancer Collaborative Group; and he isa member of the UK Department of Health’s Scientific Advisory Committee on Nutrition.
