Sleep Deprivation and Eating-Related Processes

In a series of ongoing experimental studies, I systematically evaluate how experimentally induced sleep deprivation affects processes involved in the regulation of eating. These processes include food-motivated Pavlovian-instrumental transfer effects, food cue reactivity, and effort discounting. Some findings have been published from these studies and some are in preparation.

Treatment of Insomnia

Another line of my research concerns the treatment of insomnia, especially the development and implementation of scalable, technology-aided delivery of CBT-I.

Eating Disorders Research

I have a long-standing interest in eating disorders research. Currently, eating disorders are very understudied in Hong Kong and Chinese communities. My research program aims to reduce the delay in treatment seeking by addressing the issues ranging from increasing public awareness of EDs to developing and testing scalable evidence-based treatments for eating disorders.
