BIO

I obtained my B.S. and Ph.D. in Mechanical Engineering from the School of Power and Mechanical Engineering, Wuhan University, China, in 2012 and 2018, respectively. In 2017, I was a visiting Ph.D. student at the Department of Automatic Control and Micro-Mechatronic Systems, FEMTO-ST Institute, France. From 2019 to 2020, I served as a Postdoctoral Research Fellow at the Department of Biomedical Engineering, National University of Singapore. Since August 2020, I have been an Associate Professor at the College of Mechanical and Electrical Engineering, Nanjing University of Aeronautics and Astronautics, China. My research interests include the mechanical design and precision motion control of piezoelectric nanopositioning systems and medical robots.
