Laser Metrology and Biomedicine Lab

Welcome to the Laser Metrology and Biomedicine (LAMB) Lab at The Chinese University of Hong Kong (CUHK). Our lab, directed by Prof. Renjie Zhou, works on advancing optical techniques for solving complex material metrology and biomedical problems to improve human life. Our current research projects include: (1) developing advanced optical diffraction tomography techniques; (2) building novel high sensitivity interferometric microscopy systems. As a growing lab, LAMB has multiple openings for interested candidates to apply (click here for more information).
