Dr. Yuan Ma received his bachelor’s and M.S. degrees in mechanical engineering and materials science from Tsinghua University, Beijing in 2011 and 2013, respectively. He received his Ph.D. degree in mechanical engineering from the University of California, Berkeley in 2018. Before joining the Hong Kong Polytechnic University in 2021, he worked as a postdoctoral researcher at Texas A&M University. His research interests include the micro/nanoscale mechanical and tribological behavior of human–machine interfaces, haptics metamaterials development, wearable devices with piezoelectric materials, and the application of artificial intelligence in human–machine interactions. He is specifically interested in developing advanced human–machine mechanical interfaces.
