My global health research focuses on estimating the effect of risk factors and preventive interventions on non-communicable disease incidence and mortality at the population level. This research uses empirical evidence on risk factor distributions from population health surveys and evidence on effect sizes from epidemiological studies. These methods have been and continue to be used in global analyses of the impact of risk factors on global burden of cardiovascular diseases. For the most recent publications and data from this line of research, you can visit NCDrisC. Developing methods that can improve the consistency and comparability of data sources and analytical methods across multiple risk factors is a major focus of my research in this area. I have also extended these methods to develop a novel risk prediction models for cardiovascular disease that can be easily recalibrated and applied to diverse populations (Globorisk). Another part of this research attempts to evaluate the role of risk factors on health disparities within or across countries and to estimate the potential impact of population-level preventive interventions on health disparities.
