Research Focus
Dr. Williams-Blangero’s research program focuses on the genetic epidemiology of complex diseases in minority populations. She has led the development of a number of major human population cohorts for long-term genetic research. In Nepal, she has worked with a single pedigree that includes over 2,600 members of a small ethnic group, the Jirel population. This population has been the center of collaborative research projects on parasitic disease, childhood growth and development, osteoporosis and bone-related traits, dental traits, psychiatric disease, and ocular health and disease. Dr. Williams-Blangero also works with a study population of approximately 2000 residents from a rural area of Brazil that has very high rates of Trypanosoma cruzi infection. T. cruzi is the parasitic cause of Chagas disease, which is associated with progressive cardiomyopathy. Chagas disease is found throughout Latin America and is a border health issue relevant for the Rio Grande Valley. As the Director of the South Texas Diabetes and Obesity Institute, Dr. Williams-Blangero expanded her research on the genetic determinants of risk for diabetes, obesity, and related disorders in the Jirel population and in the population of Posse, Brazil. She also established the Rio Grande Valley Family Study with support from the Knapp Community Care Foundation. With a recruitment goal of 1,000 participants, this study now includes over 550 Mexican Americans belonging to large families from the mid-Valley who are being genetically characterized for risk for diabetes and related diseases.
