Prof. Rajaratnam’s research program aims to investigate the role of the internal biological clock in the regulation of the sleep-wake cycle, and how disruption of the clock leads to sleep disorders and other physiological consequences (for example, in shift workers). With his team, Prof Rajaratnam is developing novel treatment approaches for sleep disorders that are caused by biological clock disruption. These include light and melatonin treatments. The group is also investigating the contribution of sleep disturbances and fatigue to mood disorders and impaired cognition in clinical populations.
