Welcome to the Laboratory for Innovation in Optofluidics and Nanophotonics (LION). We conduct research at the intersection between Nanophotonics and Microfluidics. Our multidisciplinary research efforts include plasmonic and resonant dielectric nanostructures for efficient nano-optical trapping, manipulation, enhanced spectroscopy, and sensing of nanoscale biological objects such as nano-sized extracellular vesicles. Our goal is to develop new optical tools that will (i) enable the understanding of the biological functions of extracellular vesicles (EVs) and (ii) drive translational biomedical applications of EVs in liquid biopsy for early detection.



We also investigate trapping-assisted nanobiosensors for the detection of biological molecules such as viruses and protein markers. A final component of our research program is on optically-resonant nanostructures for enhancement of light emission, which is crucial for the realization of quantum light sources. Through our research, we investigate innovative solutions to global challenges in life science and medicine, nanomanufacturing, and sensing. Through these activities, we educate the next generation of creative thinkers and innovators that are equipped to tackle interdisciplinary problems.
