Dr. Chau is an assistant professor of the Department of Psychiatry, The Chinese University of Hong Kong. His research interests lie in the complex interactions between mental health and neurodegeneration. The two categories have traditionally been investigated separately, but emerging evidence suggests that they are closely linked. My research explores (i) the potential of neuropsychiatric phenomena and subtle alterations of cognitive processes as prognostic biomarkers of early-stage neurodegeneration using the model of REM sleep behaviour disorder and (ii) how mental disorders affect neurodegenerative risk. I employ multidisciplinary approaches and methods in my research, with a special focus on model-driven computational analysis using multimodal neuroimaging, molecular and microbiological data.
