Helen Hobbs
Helen Hobbs is an investigator of the Howard Hughes Medical Institute and a professor of Internal Medicine and Molecular Genetics at the University of Texas Southwestern Medical Center. Additionally, she is the director of the Dallas Heart Study, a longitudinal, multiethnic population-based study of over 6,000 adults that aims to identify genetic, protein, and imaging biomarkers for early detection of cardiovascular disease as well as social, behavioral, and environmental factors that contribute to cardiovascular disease risk. By studying outliers in this population, Dr. Hobbs identified a genetic defect in PCSK9 that is responsible for low plasma LDL levels. In an interview with JCI Editor-at-Large Ushma Neill, Dr. Hobbs discusses her early scientific training at Parkland Memorial Hospital in Dallas under the direction of Donald Seldin, who guided her to scientific bench training. She also discusses the initiation of the Dallas Heart Study and the development of a therapeutic inhibitor of PCSK9 for lowering LDL.
