Prof AU Chak Leung (歐澤樑) graduated from the Faculty of Science, The University of Hong Kong with a BSc (First Class Honours) degree in Biological Sciences and obtained his MPhil degree under the supervision of Prof Patrick Y.D. Wong in the Department of Physiology, Faculty of Medicine, The University of Hong Kong. He was awarded the Commonwealth Scholarship to pursue his PhD degree in the Department of Anatomy, Faculty of Medicine, Monash University under the supervision of Prof David M. de Kretser. He joined the Department of Physiology, The Chinese University of Hong Kong in February 1983, where he served as a lecturer and later as an Associate Professor. He was a founding member of the Hong Kong Society of Endocrinology, Metabolism and Reproduction and held various positions as Council Member, Honorary Secretary, Vice-President and President. He is currently a senior lecturer in the School of Biomedical Sciences. He is an experienced teacher and has served in various capacities in curriculum design and course/programme administration, including as the Year Coordinator of MBChB Programme (2010-2020). He received sixteen “Teachers of the Years Award” (2000-2004, 2009-2019), the “Master Teacher Award” in 2004 from the Faculty of Medicine, and the Vice-Chancellor’s Exemplary Teaching Award in 2012. His current research interest is on student assessments in teaching and learning.
