RESEARCH LABORATORY

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. 

PAID POSITION OPPORTUNITIES

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 chanwais@hku.hk. This can be a full-time or part-time position for 3-9 months. Salary is competitive and commensurate with experience.

RESEARCH INTERNSHIP/UNDERGRADUATE THESIS OPPORTUNITIES

We are recruiting talented and highly motivated student interns to help with research projects on sleep and health for summer and fall of 2020. Specifically, interns who are interested in the following projects are strongly recommended to apply. Final year undergraduates who are interested in conducting your thesis study relevant to the following areas are also encouraged to contact me.

  1. Sleep and Lifestyle Intervention for Individuals with Prediabetes
    1. This project aims to evaluate the efficacy of a sleep and lifestyle intervention for improving glycemic control. Interns involved in the project will be responsible for coordinating patient visits, administering questionnaires, helping out in the delivery of the intervention.
    2. Interns involved in this project should be highly responsible, mature, detailed oriented, and have strong interpersonal skills.
  2. Development of a Digital Lifestyle Intervention
    1. This project aims to develop and evaluate the efficacy of a digital lifestyle intervention for weight loss and glycemic control. Interns will be responsible for helping with the design, coding, scripting of the digital intervention.
    2. Interns should be interested in app development and have relevant experience and skills, or be very eager to learn. Skills in graphic design and video production are appreciated.
  3. Understanding associative learning mechanisms in individuals with eating disorder symptoms/binge-eating
    1. We conduct experimental sleep restriction studies to investigate how sleep deprivation impacts learning mechanisms related to eating. Those interested in lab experimental studies and eating disorder related clinical problems are encouraged to apply.

Other general duties for interns:
Interns will be involved in conducting overnight experimental sleep procedures, administrating questionnaires and interviews, and data management. Interns are expected to work for a minimum of 10 hours per week during this internship.

General criteria for intern selection:

– Academic excellence

–  Strong work ethic

– Good organization and communication skills

– Commitment to working in the lab for more than one semester is preferable

How to apply:
If you are interested in working in our lab, please send a cover letter with your CV and academic transcript to Dr. Wai Sze Chan (chanwais@hku.hk).
