Her work with traditional village midwives in rural Tamil Nadu (1975-79) led to the analysis of child survival in contemporary India in relation to food security and conditions of women's work. In 1985, she turned to South Asian health history research, funded by the Social Sciences and Humanities Research Council (Ottawa), and is currently investigating the epistemic shifts leading to loss of understanding of the role of acute hunger in the region's malaria mortality history. Among her forthcoming work is her second monograph Uncoupling Disease and Destitution: The Case of South Asian Malaria History.
