Dr. Koon graduated from the University of Massachusetts Medical School and obtained his PhD in Biomedical Sciences (concentration in Neuroscience) in 2011. He received his postdoctoral training at the University of Queensland (UQ) in Australia, and worked as a Research Assistant Professor at the Chinese University of Hong Kong (CUHK), which he acquired two successive GRFs in 2018 and 2019. In recent years, Dr. Koon has developed a strong interest in teaching, which prompted him to become a full-time lecturer at HKU in 2019.
