Research Interests

As a trained quantitative geneticist, genetic and nutritional epidemiologist, and statistical geneticist, I am interested in health-related research and aspire to study the genetic and environmental factors that influence complex diseases such as obesity, hypertension, type 2 diabetes, metabolic syndrome, and other chronic kidney disease and cardiovascular disease risk factors. My role is to lead statistical analyses of multiple types of genetic data including next generation sequencing, array-based, and epigenetic data using advanced analytical tools. My research focuses on the disease risk of complex phenotypes with direct relevance to health disparities in the United States multi-ethnic populations. Pioneering biomedical research holds great importance for the future of human health in this country, and I desire to be an integral part of such establishment.
