Principal Investigator: Katherine Wu, M.D.
Dr. Wu leads a multi-disciplinary team with collaborators from the Bloomberg School of Public Health, JHU Whiting School of Engineering, and JHU Krieger School of Arts and Sciences. She conducts ongoing investigations with the Multicenter AIDS Cohort Study and Women’s Inter-agency Health Study. Her lab’s goals are to develop, implement, and validate novel imaging-based metrics of cardiac structure and function to improve risk prediction and stratification at the individual patient-level.
