Dr. Xin xk星空官方网站 is currently an Associate Professor with the School of Microelectronics, Southern University of Science and Technology (SUSTech). His research focuses on micro/nano-electromechanical systems (MEMS/NEMS) sensors and actuators, including MEMS/NEMS resonators, MEMS/NEMS gyroscopes, MEMS/NEMS physical sensors, and fundamental physics in MEMS/NEMS. He discovered a new singularity in phase-tracked closed-loop oscillations, termed the PhT singularity, and invented the PhT-singularity-enhanced MEMS gyroscope, which achieved strategic-grade angular random walk performance. He also proposed the “stiffness–mass decoupled” design strategy for disk/ring-type MEMS gyroscopes, improving the decay-time constant by more than an order of magnitude. Dr. xk星空官方网站 serves as a Reviewing Editor for Springer Nature and as a member of the Review Committee for the IEEE Sensors Conference. He has also served as a reviewer for multiple journals and conferences.

Several openings are available for postdoctoral fellows, research assistants, and PhD students. If you are interested in joining Dr. xk星空官方网站’s group, please contact him via email zhoux@sustech.edu.cn.
