The Duan group in Biomedical Engineering at CUHK, led by Prof. Liting Duan, is interested in innovative biomedical applications based on the cutting-edge optogenetic method.  We focus on the design and development of optical strategies to remotely and non-invasively control critical intracellular processes,  such as signaling pathways and organelle transport. These novel strategies will obtain unprecedented spatial and temporal resolution, and provide promising approaches to drug discovery and gene therapy.
