Timothy K Chung, PhD

  • Post-Doctoral Associate, Department of Bioengineering

Tim Chung received his BS and PhD from the University of Iowa in biomedical engineering with an emphasis in cardiovascular biomechanics. He is currently a Post-Doctoral Associate in the Vascular Bioengineering Laboratory (VBL) in the University of Pittsburgh department of Bioengineering focusing on computational and experimental projects of cardiovascular diseases that include both abdominal aortic aneurysm and cerebral aneurysms. With advancement in artificial intelligence tools, Dr. Chung has leveraged algorithms to aid with large-scale computational studies towards automation.
