Forrest Cheung
PhD
Postdoctoral Research Associate in Sleep Medicine
My research focuses on
- Shift work disorder
- Delayed sleep-wake phase disorder
- Circadian rhythm and insomnia
Biography
I hold a BSocSc in Psychology and Counselling from the University of Hong Kong. I further advanced my study by pursuing a PhD at the Sleep Research Clinic and Laboratory, HKU. My doctoral project focused on investigating the role of circadian rhythms in the aetiology and pathophysiology of insomnia in adolescents, as well as exploring the therapeutic potential of bright light therapy.
Research Summary
My current work, supported by the NIHR, involves developing and testing a behavioural intervention for shift work disorder in healthcare workers in the NHS. By addressing the unique sleep challenges faced by NHS workers with irregular hours, our goal is to develop a personalised, evidence-based approach that improves sleep quality and enhances overall well-being. The intervention integrates circadian-based strategies and behavioural techniques to promote adaptation to shift work. Ultimately, my work advances the broader understanding of circadian rhythm disorders and contributes to practical solutions for those affected by sleep and circadian rhythm disruptions.
