Dr. Jian Zhu is an assistant professor at the department of Mechanical Engineering, NUS. His current research interests lie in Soft Robots, Soft Active Materials, and Smart Materials and Structures. Before moving to Singapore, he worked as a postdoctoral fellow at Harvard University, USA. He received a Ph.D. degree in Mechanical Engineering at University of Alberta, Canada in 2008, and was then awarded a NSERC Postdoctoral Fellowship by Natural Sciences and Engineering Research Council of Canada in 2008. He worked on climbing robots at City University of Hong Kong in 2002, which can take the place of human beings to clean the windows of the high-rise buildings.
