Professor Jane Fisher has made significant, sustained contributions to health and medical science in the fields of mental health, women’s health, and global health. Her research on the social and psychological determinants of perinatal mental health problems has informed prevention and early intervention programs in Australia and internationally. It led to the inclusion of maternal mental health in World Health Organization and USAID policies. Through her sustained research partnership with colleagues in Vietnam, she has developed an effective low-cost intervention for early childhood development and maternal health applicable in all resource-constrained settings.
