  • Understanding genes, their regulation and function with emphasis on development.
  • The genetic and molecular basis of inherited and degenerative skeletal disorders.

The Mission of her group is to make significant contributions through multidisciplinary synergistic partnerships and cutting edge science. Her group aspires to reach the long term Vision of “Bench to Bedside” research, translating discovery to the clinic. Some key contributions of her group are:

  • Sox2 as a master “hearing gene”;
  • Molecular insights into the function of Sox9, the master gene for development of cartilage;
  • Discovery of a mechanism that explains how mutations causing ER stress in chondrocytes, can affect their differentiation and cell death and thereby cause skeletal disorders;
  • Showed that chondrocytes become osteoblasts during bone formation and repair, thereby resolving a century-long debate about this possibility.

Professor Kathryn Cheah is a developmental geneticist. She received her PhD in molecular biology from the University of Cambridge, UK, was a postdoctoral fellow in the University of Manchester and Imperial Cancer Research Fund, UK. In HKU she has served as Head, Department of Biochemistry and Director of the Centre for Reproduction, Development and Growth. She was awarded a Croucher Foundation Senior Fellowship (2000) and is an elected Fellow of the global academy for the advancement of science in developing countries, The World Academy of Sciences (TWAS). In 2021 she was elected as Member of the Hong Kong Academy of Sciences. She was awarded the British Society for Matrix Biology Medal Lecture 2022 for her contributions to matrix biology. She was elected Associate Member of EMBO (European Molecular Biology Organisation (https://www.embo.org/about-embo/membership/) in 2023.

The driving motivation of her research is the realisation that, with an ageing population worldwide, genomic and regenerative medicine will play critical roles in helping to preserve healthy growth and quality of life. She uses human and mouse embryonic stem cells and genetically modified mice as models to study development and disease and develop therapeutic approaches for disorders of cartilage (e.g. osteoarthritis) and low bone mass (e.g. osteoporosis) and intervertebral disc degeneration.

She and her team pioneered the introduction of transgenic and knockout mouse technology to Greater China and Hong Kong.

She is passionate about contributing to the public and professional understanding of science and promoting the international profile of Hong Kong science through organizing international symposia and Croucher Foundation Advanced Study Institutes. She has served as Biology & Medicine Panel member on the Research Grants Council and as Biology Panel Member for the University Grants Committee Research Assessment exercises. She is currently a panel member of the Health and Medical Research Fund.

Internationally she is Senior Editor for eLife and also serves on the Editorial Board of Journal of Orthopedic Research, as Editorial Advisor: Emerging Topics in Life Sciences, on the Advisory Board, Natural Sciences.

She was elected President of the International Society for Matrix Biology 2006-2008; the founding President of the Hong Kong Society for Developmental Biology (HKSDB) (2004-2013); Hong Kong representative for Asia-Pacific Developmental Biology Network and the International Society of Developmental Biology; appointed Senior External Fellow of the University of Freiberg Institute of Advanced Studies 2011-2012; elected member, Board of Directors of the International Society of Differentiation (2012-2018). Currently she serves on the Hong Kong Advisory Board of the Gordon Research Conferences (GRC) and the GRC Board of Trustees Conference Evaluation Committee. She was Chair of the Bid Committee for the ISSCR (International Society for Stem Cell Research) Annual Meeting 2025 in Hong Kong. Currently she serves as co-Chair with Eugenia Piddini of the ISSCR 2025 program committee.
