I am a formal demographer who works on the demography and epidemiology of Africa and developing new methods for population sciences.  Right now I am working on:

• Improving the 'verbal autopsy' method used to quantify the burden of disease for populations without full coverage vital statistics systems - work with colleagues at The Ohio State University, the University of Washington, the London School of Hygiene and Tropical Medicine, the CDC, the Swiss Tropical and Public Health Institute, the WHO, and the 'Data for Health’ Initiative
• Mapping child mortality at the subnational level through time using household survey data in countries without full coverage vital statistics systems - work with colleagues at the University of Washington and UNICEF
• Developing new population indicator measurement strategies and statistical methods to implement them - work with colleagues at the University of Washington

Fertility and Mortality: variety of projects investigating levels and trends in fertility and mortality, mostly in Africa, and sometimes building models of age schedules of fertility and mortality that can be used widely as inputs to other analyses - work with a variety of colleagues at The Ohio State University and elsewhere
