SCOPUS IDBiography
Prof. Rachel Chun obtained her Bachelor degree in Optometry with first class honours from The Hong Kong Polytechnic University (PolyU) in 2003. She then received a scholarship from PolyU for pursuing postgraduate study and obtained her PhD degree in 2010. Her PhD study was the role of cAMP and ApoA1 in avian eye growth using a proteomic approach. Her dissertation was designated a Distinguished Thesis by the Faculty of Health and Social Sciences of PolyU. Upon receiving her PhD, she participated in teaching as an Instructor in the School of Optometry from 2011 to 2013. Since then, she has gained clinical experience in myopia control as an Optometrist and Senior Optometrist in the PolyU Optometry Clinic. She continues to devote herself to conducting clinical studies and trials based on the knowledge gained from basic science research. In 2020, she joined the School of Optometry of PolyU as a Research Assistant Professor.
