William Wu received basic medical science education at HKU during his MMedSc and MPhil studies and obtained PhD in Medical Sciences from CUHK in 2009. He received post-doctoral training and was later appointed as Research Assistant Professor in the Institute of Digestive Disease, CUHK. He joined the Department of Anaesthesia and Intensive Care as Assistant Professor (Non-clinical) in 2014 and was promoted to Associate Professor (Non-clinical) in 2018. His research interests include cancer biology & genomics, infection/sepsis, and pain mechanism. As of May 2021, he has published over 310 articles in peer-reviewed journals and 6 book chapters, with over 15,000 citations and an h-index of 59 (Scopus). He was conferred the Young Researcher Award by CUHK, the First-class Higher Education Outstanding Scientific Research Output Award (Natural Science) by the Ministry of Education, and the Second-class State Natural Science Award. He was also admitted as a Fellow of three Medical Royal Colleges (FRCPath, 2014; FRCP Edin, 2018; FRCPS Glasg, 2019). As Principal Investigator, he has presided over 20 million HK dollars of external funding, including 1 NSFC, 3 SZSTI Basic Research Programs, 3 RGC-ECS/GRF and 5 HMRF/RFCID.
