Professional background
Dr. Tsui is a consultant academic geriatrician and acute medical physician practising at University College London and St Pancras hospitals. His main clinical interest is in the care of frailer older patients who have experienced acute illnesses such as infections, resulting in confusion known as delirium or worsening physical function, often in the context co-existing cognitive impairment or dementia.
He is the current holder of a NIHR (National Institute for Health and Care Research) research grant and undertakes his research programme at the MRC Unit for Lifelong Health and Ageing at University College London (UCL). He studied at the University of Oxford medical school, completed his post-graduate medical training in London and received his PhD from UCL in population epidemiology and machine learning models. In his research, he is interested in longitudinal, deep phenotyping prediction and inferential models of acute illness decompensation. His aim is to apply novel approaches to better understand, diagnose and optimise treatments, improving short to long term outcomes, while emphasising the need to understand priorities from the context of the patient.
