He received his PhD in Mechanical Engineering from MIT in 2002. His PhD research at MIT was to develop smart personal mobility aids and health monitoring systems for the elderly, with his main contribution in the areas of omni-directional mobility design and adaptive shared control for human machine interaction. He then worked in DSO National Laboratories of Singapore as a Principal Member of Technical Staff. His research areas in DSO included exoskeleton and humanoid robots as well as intelligent ground and aerial robots. Dr. Yu joined Department of Bioengineering of NUS in September 2010. His current research focus is on robotics for neurorehabilitation, especially on using exoskeleton systems and smart mobility aids for patients with stroke and Parkinson's Diseases. His is collaborating with NUHS, SGH, DSO, MIT, UPMC of France, and Maebashi Institute of Technology of Japan for his research.
