We are an interdisciplinary research group working across chemistry, physics, materials science, biomedicine, optical engineering, and precision instrumentation. Our research focuses on nanophotonics, bringing together fundamental studies, methodological innovation, and practical applications. We investigate the optical and electronic properties, interfacial dynamics and underlying mechanisms of nanocomposite materials, such as Gold (Au) based nanomaterials, as well as their applications in energy, environment, and biomedicine. Our material systems include metal/semiconductor based nanocomposite materials, biomedical materials, and nonlinear optical materials. Topics include time-resolved & nonlinear optical spectroscopy, photo-induced chemical & physical processes, photocatalysis, light based biosensing, bioimaging and precision therapy. We welcome students and colleagues who are curious, motivated, and collaborative. Join us! |
