Dr. Jiangbo (Tim) Zhao is an Associate Investigator of the Australian Research Council Centre of Excellence in Nanoscale Biophotonics and a Research Associate at University of Adelaide. He is from Inner Mongolia, China, and holds Ph.D from Macquarie University, Australia. His research interests lie in the interdisciplinary area of photonics, materials, and biomedical science, focusing on light-matter interactions, luminescence in solid state and nanoscale structures, and photonics-based devices for practical applications. His experimental and theoretical work in lanthanide-doped upconversion nanocrystals has led to a better understanding of upconversion luminescence, and to broadband advanced applications from single molecule imaging, rare-event cells detection, remote fibre sensor, to security printing. Tim’s primary research in nanoparticles-embedded glass/fibre provides insight in their chemical, structural and optical properties and is expected to impact applications in the areas of optics and photonics (e.g., light source), imaging and sensing, energy saving (e.g., smart window), and human health (e.g., diabetes, neuroscience).
