Biography

Xiaosheng Gao received his PhD from Brown University in May 1998 with a major in solid mechanics and two minors: one in materials science and the other in applied mathematics. He then worked as a postdoctoral research associate at the University of Illinois at Urbana-Champaign. He joined the University of Akron as an assistant professor of Mechanical Engineering in January 2001, became an Associate Professor in May 2006 and a professor in May 2011. His other appointments including as an assistant professor at the Northwestern Polytechnical University (China) from July 1990 to August 1992, as a visiting scholar at the Royal Institute of Technology (Sweden) from November 1996 to May 1997, as a visiting professor at the National University of Singapore in summer 2005, and as an ONR Summer Faculty Fellow in 2006 and 2007.


Research Accomplishments

Dr. Gao’s research areas include mechanics of materials and structures, computational mechanics, fatigue and fracture mechanics, multi-scale modeling of damage and failure and material characterization with microstructure. In recent years he has worked extensively on developing mechanism-based models to simulate material failure process and to predict fracture of structural components. This research bridges the macroscopic continuum mechanics and the microscopic aspects of materials science. The results provide guidelines for safer and more economic design and operation of high-performance of engineering structures. He has authored over 80 archival publications (journal papers, book chapters and conference proceedings) in the areas of his research. He has also presented his research findings at numerous international conferences and workshops and given seminars at various institutions. He received the Office of Naval Research Young Investigator award in 2002. His research has attracted funding from several federal and state agencies as well as industry. He has served as a reviewer for over 30 international journals and reviewed proposals for several government agencies.
