Brief Description

Dr. Yao received his BEng and MEng degrees in Solid Mechanics from Tsinghua University in 2000 and 2002 respectively. Subsequently, he went to Germany and studied at the Max-Planck Institute for Metals Research. In 2006, he obtained his Doctor degree in Chemistry from Universität Stuttgart. Then he worked at Brown University (2006-2007) and subsequently Massachusetts Institute of Technology (2007-2010) as a postdoctoral Research Associate. Before Joining the Hong Kong Polytechnic University in 2011, he had worked at Sun Yat-sen University for one year.

The research interests of Dr. Yao include bio-inspired mechanics and materials, nanomechanics, contact mechanics, mechanical characterizations of biomaterials, mechanical behaviors of energy materials. So far, he has published more than 45 papers in refereed journals including PNAS, Scientific Reports, JMPS, Nanoscale, and Carbon and so on with total citations reaching > 2000 and H-index=22. Dr. Yao is the awardee of the Research Grant Achievement Award (2014) and Merit Award in Research and Scholarly Activities (Individual) (2014/15) of the Engineering Faculty of PolyU.
