Research

The PMNP Laboratory (Yan research group) is interested in high-accuracy, high-efficiency, resource-saving manufacturing technologies. Through micro/nanometer-scale material removal, deformation, and surface property control, new products with high added value are provided to micromechanical, optical, optoelectronic, and biomechanical applications. We are exploring multidisciplinary R&D by interfacing with mechanical science, physics, material science and nanotechnology. Research projects are active in the following areas.
