Biographical Sketch

Kewei Li received his B.S. and M.S. degrees both in Mechanical Engineering from Xiangtan University (2005) and Shanghai University (2008), respectively. He investigated the structural responses of spherical plain bearing for his Master’s thesis. In 2008, he proposed the first Finite Element model of spherical plain bearing with detailed description of self-lubricating composite liner. After completing his Master's degree, Kewei started his Ph.D. research in Computational Biomechanics field at Dr. Wei Sun’s Tissue Mechanics Laboratory in University of Connecticut. In this research, Kewei developed the first computational model of transcatheter heart valve to quantify the effects of unique valve designs (for example, no stent deflection), leaflet thickness, and tissue compliance on structural response and deformation of transcatheter heart valve in both circular and elliptical configurations. Later on, he proposed a probabilistic computational scheme to evaluate the impact of leaflet geometry on the valve peak stress. Recently, Kewei worked on fluid-structure interaction simulations of transcatheter heart valve using the smoothed particle hydrodynamics method. In 2013, he successfully defended his Ph.D. thesis titled "Biomechanical Simulations of Transcatheter Aortic Valve".

After finishing his Ph.D. degree, he worked as an R&D Intern in the Computational Biomechanics field at Dassault Systèmes Simulia Corp., Providence, Rhode Island.

He has co-authored numerous journal publications and one world patent on heart valve design. His research interests include cardiovascular solid mechanics, computational biomechanics and experimental methods for testing of soft tissues.
