RESEARCH LABORATORY

Why and how do people change? Any why do we perseverate on behaviors that deemed harmful to us? Dr. Wai Sze Chan’s research aims to address these fundamental questions in the field of clinical psychology and translate this knowledge into effective and scalable interventions.

Dr. Chan directs the Sleep, Self-regulation and Health (SLASH) Research Laboratory. Her current studies are externally funded by the General Research Fund and Health and Medical and Research Fund (see list). They include studies on sleep restriction and its effect on the regulation of eating behavior and other cue-elicited behaviors and the development and evaluations of clinical interventions for disordered eating, weight management, and insomnia.

*I am currently accepting PhD students and recruiting a postdoctoral fellow/research assistant. Please contact me at chanwais@hku.hk if you are interested.
