Our Research

Insufficient sleep has become a health epidemic. It is associated with numerous adverse health and cognitive consequences, such as impaired attention in students and increased risks for dementia in older adults. We hope that by studying the contribution of sleep to neurobehavioural functions, we can find ways to improve sleep health and thereby help maximise cognitive potential and improve quality of life across the lifespan.


Our research targets various age groups:


  • Children:

Investigate the contribution of various sleep features, such as sleep macro- and micro-structure to cognitive development, academic performance and behavioural problems


  • Adolescents:

Characterise decrements in neurobehavioural functions among sleep-deprived teens in our search for an optimal and feasible schedule that enables the best possible cognitive outcomes


  • Adults:

Investigate the impact of night-to-night variability in sleep duration on cognitive performance and glucose metabolism, so as to determine whether having a stable or variable sleep schedule can help to better offset some of the cognitive and metabolic impairments induced by sleep restriction across multiple nights
