1. Qing-Hua Qin's research interests include computational mechanics, biomechanics, and multifield materials and structures. He received his Bachelor of Engineering degree in mechanical engineering from Xi'an Highway University (currently Chang An University), China in 1982, earning his Master of Science degree in 1984 and Doctoral degree in 1990 from Huazhong University of Science and Technology (HUST) in China. Both degrees are in applied mechanics. He joined the Department of Mechanics as an associate lecturer at HUST in 1984, and was promoted to lecturer of mechanics in 1987 during his PhD candidature period. After spending ten years lecturing at HUST, he was awarded the DAAD/K.C. Wong research fellowship in 1994, which enabled him to work at the University of Stuttgart in Germany for nine months. In 1995 he left HUST to take up a postdoctoral research fellowship at Tsinghua University, China, where he worked until 1997. He was awarded a Queen Elizabeth II fellowship in 1997 and a Professorial fellowship in 2002 at University of Sydney and stayed there till December 2003, both by the Australian Research Council, and is currently working in the Department of Engineering at the Australian National University, Australia. He was appointed a guest professor at HUST in 2000. He was also appointed a Member of editorial board of the Chinese Journal of Computational Mechanics from 2003 and an associate Editor of the International Journal of Tomography and Statistics from 2005. He has published more than 160 scientific papers and four books in the field of applied mechanics, and was a recipient of the J.G. Russell Award from the Australian Academy of Science and a Natural Science Prize (2nd grade) from the Ministry of Education of China. 2. Qing-Sheng Yang is a professor of engineering mechanics at the Department of Engineering Mechanics of Beijing University of Technology. He received his doctorial degree in computational mechanics at Dalian University of Technology in 1992. Then he worked as a postdoctoral researcher at Dalian University of Technology and Tsinghua University from 1992 to 1996. In 1996, he joined Northern Jiaotong University as an associate professor of structural engineering and in 2000 he moved to Beijing University of Technology as a professor of engineering mechanics. From 2001, he serves as deputy dean of the department. His research interests include micromechanics of composite materials, computer analysis of engineering structures, coupled thermo- electro- chemo- mechanical behavior of biomimetic materials and numerical methods. He is an author of more than 100 scientific papers and 3 academic books. From August, 2002 to July, 2003, he had worked as a visiting professor at Department of Mechanical Engineering of University of Siegen, under support by Henrich Hertz Foundation. From August 2005 to Jan. 2006, he had worked as an adjunct professor at The Australian National University.
