This project/program will gather a few different research initiatives of the P.I. and her interlocutors along the lines developed in previous research projects in the convergence of medical anthropology and social history of medicine. Data collected during past projects deserve further analysis and discussion. A comparative framework gathering on-going or recent research projects provides the ideal environment for further theoretical developments and meaningful contributions. Formal and informal international partnerships involving colleagues from the UK, US, Brazil, India and other places were substantially developed during previous projects and academic events; they will be the main contributors for this comparative endeavour. The topics covered by the project will include the broad field of tropical medicine under colonialism and more precisely the management of epidemics in Africa and Asia; eugenics; racialism; adaptation, population displacement, forced migrations and  engineered settlements; cross-cultural studies on healing and religion in post-colonial settings.
