My research is organized primarily around two main areas: (1) formal demography; and (2) understanding health disparities across and within populations. In the area of formal demography, I have designed new methodologies for better understanding mortality levels and trends, and for studying their impact on population growth and aging. I have also made contributions in the area of model age patterns of mortality and indirect estimation methods. In the area of health disparities, I have examined the burden of disease among the global poor. I have also studied the health of vulnerable ethnic, religious, and migrant groups in a range of populations, including India. A related interest has been the analysis of the health crisis in the former Soviet Union, with a special focus on the Central Asia region.
