Dr. Wai Sze Chan directs the Sleep, Self-regulation and Health Research Laboratory. Our mission is to enhance the understanding of the processes underlying health behaviour changes and to translate this knowledge into effective and scalable interventions. Our research draws from learning theories and self-regulation theories of behaviour. With a focus on sleep, our current research aims to unravel the mechanisms underlying the link between sleep and behavioural health and to optimize the use of sleep interventions to improve the wellbeing of vulnerable individuals. 


We are recruiting a full stack JavaScript developer to join our development team for a digital lifestyle intervention for type 2 diabetes. This digital intervention will be built on an open-source platform. If you have relevant experience and qualification, please send your CV to Dr. Chan at This can be a full-time or part-time position for 3-9 months. Salary is competitive and commensurate with experience.


We are looking for research interns to work in the Sleep, Self-regulation, and Health lab ( We conduct experimental and intervention studies concerning behavioral regulation, sleep, and mental and physical wellbeing.  

Interns will work closely with other members of the lab on different aspects of one or more ongoing research projects including:

– conduct literature review

– prepare experimental materials

– administer experimental procedures

– assist clinical psychologists in conducting assessments and scorings of questionnaires in community and university settings

Intern selection:

– Strong academic competence is a must

– Effective communication and interpersonal skills are necessary

– Strong organization skills and attention to detail are required

– Fluency in written and spoken Chinese (Cantonese) and English is required

– Prior lab experience is an advantage

Interns are required to work for approximately 12 hours/week and must commit to two semesters.

Highly motivated and capable individuals will have the opportunity to contribute to data analysis and manuscript writing and earn authorship credits.

Credit-bearing research internship courses, PSYC2072, and PSYC2073 are available when the autumn semester starts. 

If you are interested in getting involved in the lab, please email Dr. Wai Sze Chan ( with your CV and academic transcript. Interviews take place in early August. Training begins in late August.
