Welcome to the Laser Metrology and Biomedicine (LAMB) Group at The Chinese University of Hong Kong (CUHK). Our group works on advancing optical techniques for solving complex biomedical problems to improve human life. Currently, we focus on building label-free optical imaging systems for long-term live cell imaging and mapping cell functional activities. Specifically, we are developing advanced optical diffraction tomography techniques and novel high sensitivity interferometric microscopy systems.   

LAMB, as a growing group, has multiple openings for graduate students to join in Fall 2018 with full financial support (~ 16,000 HK$ monthly stipend). Exceptional candidates are also highly encouraged to apply for the prestigious Hong Kong PhD Fellowship Scheme (HKPFS) before December 1 of this year (consult with Prof. Zhou before applying; click here for more information). Awardees of the HKPFS will be provided a monthly stipend of 20,000 HK$ and a conference travel allowance of 10,000 HK$ per year. We also constantly look for exceptional postdocs and short-term researchers. Should you choose to join LAMB@CUHK, you will work on high impact interdisciplinary research work ranging from optics and mechanics to biology and medicine. Positioned for world-leading cutting-edge research, LAMB group has collaborations with world-leading research institutes such as MIT, UIUC, Johns Hopkins, UConn, and Zhejiang U. Prof. Zhou will support students and researchers for academic exchanges with collaborating institutes. If you have an interest in joining our group, please do not hesitate to contact the group leader Prof. Renjie Zhou at rjzhou at cuhk dot edu dot hk with your CV and a short introduction to facilitate our communication.
