Lei Ren received his B.Eng., M.Eng. in Mechanical Engineering and Ph.D. in Vehicle Engineering from National Laboratory of Automotive Dynamic Simulation, Jilin University, China. He then came to Centre for Rehabilitation and Human Performance Research, University of Salford, and worked on a UK Ministry of Defense project on human locomotor biomechanics, and received a Ph.D. in Biomechanics. Thereafter, he worked at Structure and Motion Laboratory, Royal Veterinary College, University of London, as a BBSRC research fellow on comparative musculoskeletal biomechanics. From 2007 to 2010, he was with Centre for Robotics Research, Division of Engineering, King's College London as a lecturer. Dr. Ren joined the School of MACE, University of Manchester in 2010, and also works as a research scientist at Structure and Motion Laboratory, University of London. He is the founding member of the International Society of Bionic Engineering, and also a member of the International Society of Biomechanics, European Society of Biomechanics, the Society of Experimental Biology and European Society for Movement Analysis in Adults and Children.
