About Professor Zhang 關於張教授

Professor Zhang Xiujuan is a clinician-scientist with expertise in research on myopia research, ocular epidemiology, and blindness prevention. She has the research focus on myopia and its intervention, particularly low-concentration atropine eye drops for myopia control. She graduated from the Chinese University of Hong Kong, with a PhD degree in Ophthalmology and Visual Sciences. She has led five ocular epidemiological studies, involving a total of 10,000 subjects, for her PhD projects. She coordinated the Hong Kong Children Eye Study, a comprehensive investigation involving 40,000 children to investigate the epidemiology of myopia and paediatric ocular diseases. Her primary involvement in clinical trials of low-concentration atropine has been instrumental in advancing the treatment and prevention of myopia.
張秀娟教授是一位臨床醫生兼科學家，專注於近視、眼科流行病學和防盲研究。她的研究重點為近視及其干預措施，尤其是用於控制近視的低濃度阿托品眼藥水。她於香港中文大學修畢眼科及視覺科學博士學位，博士期間她帶領了五項眼科流行病學研究項目，涉及共計10,000名參加者。她曾協調組織香港兒童眼科研究，是一項涵蓋了40,000名兒童的全面檢查，以研究近視和兒童眼科疾病的流行病學研究。她在低濃度阿托品臨床試驗中的主要參與對推進近視治療和預防起到了重要作用。

Research and Awards 研究及獎項

As a Principal Investigator, Professor Zhang has obtained seven grants, including four external competitive grants, with funding of HK$7,680,000 from 2020 to 2024. She has more than 60 publications and published in international journals, including JAMA, The Lancet Global Health, JAMA Network Open, Ophthalmology, NPJ Digital Medicine, and JAMA Ophthalmology. She is the recipient of local and international awards and honours in research and professional services including the Global Fellowship Award from the University of St Andrews in the United Kingdom in 2023, the Outstanding Research Impact Award from the Chinese University of Hong Kong in 2022 (Co-I) and Hong Kong Outstanding Youth Volunteer Group Award. The intelligent glasses ‶My-O-Analyser″ as an objective measure for lifestyle monitoring, co-invented by Professor Zhang, has obtained 4 international awards, including a Silver Medal in the Geneva International Exhibition of Inventions. 

張教授在2020年至2024年間以首席研究員獲得七項資助，其中包括四項來自校外資助，總金額為7,680,000港元。她在《美國醫學會雜誌》、《柳葉刀全球健康》、《JAMA Network Open》、《眼科學》、《NPJ數字醫學》和《美國醫學會雜誌眼科學卷》等國際期刊發表了60多篇論文。她在研究和專業服務方面獲得本地和國際獎項和榮譽，包括英國聖安德魯斯大學的全球科研者獎（2023年），香港中文大學的傑出研究影響獎（共同研究員）（2022年），以及香港傑出青年義工團隊獎。由張教授共同研發的——用於監測生活方式的智能眼鏡「My-O-Analyser」——已獲得四項國際獎項，包括日內瓦國際發明展的銀獎。
