Undergraduate Research Training Programme

  • We warmly invite UG students to join our research group, where they will benefit from systematic academic research training. This opportunity is especially advantageous for those aspiring to pursue a Master’s or PhD degree. At the moment we have several projects for UG students: 1. Ultra-precision motion control and its application in lithographic equipment.
