Biography
Prof Desmond Yat-Hin Yap joined the University Department of Medicine after his graduation from MBBS at the University of Hong Kong. He later pursued his Doctor of Medicine (MD) and Doctor of Philosophy (PhD) degree at his alma mater, both along the study of the immunopathogenesis and treatment of lupus nephritis.
Prof. Yap dedicated his research to immune-mediated glomerular diseases, focusing on lupus nephritis and membranous nephropathy. Prof Yap was the co-first author for the Asian Guidelines for the management of lupus nephritis - jointly published in the official journals of regional nephrology and rheumatology societies [Nephrology (Carlton) 2014 & Int J Rheum Dis 2013], and also took a leading role in the formulation of the 2024 APLAR Consensus on the Management of Lupus Nephritis [Int J Rheum Dis 2024]. His research findings have also contributed to the latest KDIGO Clinical Practice Guideline for Glomerulonephritis 2021. He received the Hong Kong Society of Nephrology (HKSN) Young Investigator Award in 2009 for his research on serum immunoglobulin binding activity to human mesangial cells in lupus nephritis. Funded by the Li Shu Pui Clinical Fellowship (2014-2015), Prof Yap worked as a research fellow at the Fiebiger-Nikolaus Centre, Friedrich-Alexander University, Germany to study B cell homeostasis in immune-mediated diseases. Prof Yap was awarded the LKS Faculty Teaching Medal in 2019, in recognition of his contributions in teaching and curriculum development. In 2021, he was awarded the prestigious Sir David Todd Lectureship by the Hong Kong College of Physicians for his work on lupus nephritis research.
Other key research interests of Prof. Yap pertain to the management of complications in acute and chronic kidney diseases, and he was the first author of various local/regional guidelines for the management of anaemia, hyperkalaemia and infective complications in renal failure patients [Nephrology (Carlton) 2021; Nephrology (Carlton) 2024; Hum Vaccin Immunother 2025].
Prof Yap holds leadership positions in various local-regional and international nephrology societies - currently serving as the Honorary Secretary of HKSN, Honorary Treasurer of Asian Pacific Society of Nephrology (APSN), and Regional Board Member (North and East Asia) of the International Society of Nephrology (ISN). Prof Yap has published over 190 peer-reviewed articles in various internationally renowned journals, and is currently Subject Editor for Nephrology (Carlton), the official journal of the APSN.
