Dr. Tseng is Professor of Surgery at the University of California San Francisco and Chief of Cardiothoracic Surgery at the San Francisco VA. Her academic research interests over the past 19 years have involved biomechanics, fluid dynamics, and computational simulations of aortic root surgery, including aortic stenosis, transcatheter aortic valves, Ross operation, ascending thoracic aortic aneurysm (aTAA) and dissection. She has been an NIH R01 funded surgeon-scientist investigating the biomechanics of ascending thoracic aortic aneurysms to determine better predictors of type A dissection than maximum diameter. Through the VA, she will investigate the impact of aTAA biomechanics on dissection, rupture, and death. Her clinical expertise is in structural heart disease and aortic surgery, including transcatheter aortic valve replacement, mitraclip, minimally invasive surgical valve repair and replacement, and ascending thoracic aneurysm repair. She has published >100 scientific papers and book chapters. Dr. Tseng serves on the Society of Thoracic Surgeons (STS) Workforce for New Technology and Workforce on Health Policy, Advocacy, Reform, American Association for Thoracic Surgery (AATS) Research Foundation, and American Heart Association (AHA) Cardiovascular Surgery and Anesthesia Council. She is completing her tenure as the Chair of the Thoracic Surgery Foundation Research Committee.
