Dr 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). His group develops novel treatment approaches for sleep disorders that are caused by biological clock disruption. These include light and melatonin treatments. He is also investigating the contribution of sleep disturbances and fatigue to mood disorders and impaired cognition in clinical populations.
Dr Bei is a Clinical Psychologist and sleep researcher. She is interested in the individual differences in sleep-wake behaviours, the relationship between sleep and mental health, and psychological interventions for better sleep. Her clinical work has focused on mood, anxiety, and sleep disorders in adult, adolescent, and perinatal populations.
Dr Stone is a Research Fellow at Monash University. Her research interests include individual variability in circadian rhythms and sleep, the role of circadian disruption and light exposure on health and performance, and computational modeling approaches for circadian phase estimation in the real world.
Dr. Phillips is a Senior Lecturer within the Turner Institute for Brain and Mental Health in the School of Psychological Sciences at Monash University. His research vision is to understand the biology, behaviour, and functions of sleep and circadian rhythms through physiologically based modelling. He has developed mathematical models and health-based metrics that are widely used in the sleep and circadian fields. His work is closely integrated with experiments, so that model predictions can be tested and so that additional insights can be gleaned from data.
Dr. Josh Wiley is a behavioural medicine researcher currently at Monash University. His research includes basic science and applied intervention work. In basic science, his work focuses on understanding the daily and longitudinal dynamics of sleep, psychosocial factors and health. His intervention research focuses on accessible and feasible sleep/behavioural and emotion regulation interventions with potential
for broad dissemination.
Prof. Carskadon is a world leader in sleep research. She is a Professor in the Department of Psychiatry and Human Behavior at Brown University, and Director of the Sleep and Chronobiology Research Lab at E.P. Bradley Hospital. Her current research includes an evaluation of how sleep and circadian timing influence smell, taste, food choices, and food consumption in overweight and normal weight teens and development of “smart lighting” to improve academic outcomes in secondary school students. Her team is also investigating the impact of serial nights of alcohol use in adults on sleep and next-day cognitive performance.
Dr. Klerman is Director of the Analytic Modeling Unit within the
Division of Sleep Medicine at BWH. Her current research focuses on the areas of: (1) the interaction of endocrine, circadian and sleep rhythms in normal and pathological states (2) mathematical modeling of sleep, circadian system and markers of its function.
Members of the Analytic and Modeling Unit systematically and mathematically explore many aspects of the sleep and circadian rhythms. The results have implications for the design and analysis of future circadian experiments as well as reinterpretation of earlier studies. This work is part of a cycle of experimental work-mathematical modeling and predictions-experimental work.
The Circadian Physiology Program focuses on basic and applied aspects of human circadian biology. Their translational approach includes use of a range of techniques including epidemiology, field-based
physiological studies and inpatient intensive physiological monitoring. They have a particular interest in human circadian photoreception and the effects of light on the circadian pacemaker and other non-image forming responses.
Their studies include investigations of the effects of timing, duration, intensity and wavelength of light exposure on circadian resetting, melatonin suppression and the acute alerting effects of light. They also study visually impaired individuals under field and laboratory conditions to examine the effects of the severity and type of blindness on circadian photoreception, the periodicity of the circadian pacemaker and development of circadian rhythm sleep disorders.
These basic studies have led to the development of novel therapeutic strategies to treat non-24-hour sleep wake disorder, Advanced- and Delayed Sleep Phase Syndrome with appropriately-timed melatonin administration in blind patients. They have also recently begun to examine the role of visual impairment on endocrinology and breast cancer risk in blind women.
Anthony is a PhD (Clinical Neuropsychology) Candidate and Provisional Psychologist at the Turner Institute for Brain and Mental Health at Monash University. He is interested in investigating the effects of light and sleep regularity on cognitive development.
Sinh is a PhD student in the Turner Institute for Brain and Mental Health at Monash University. His main research interests include the social-behavioural determinants of adolescent sleep and development, as well as the longitudinal impacts of sleep beliefs and attitudes on sleep and circadian outcomes.
Evan is a PhD (Clinical Psychology) Candidate and Provisional Psychologist at the Turner Institute for Brain and Mental Health at Monash University. His main research interests include examining the relationships between sleep, mood and mental health in adolescents.
Dr. Monika Raniti
Clinical Research Assistant
Dr Raniti's main research interests include the development of sleep and other health interventions for the prevention and early intervention of mental health problems, particularly during adolescence, the perinatal period, and in individuals experiencing chronic pain and fatigue. She is also interested in the role of educational institutions and primary health care services in the implementation and dissemination of these interventions.
Monika is excited to be working with the participants of CLASS study so we can learn more about the effect of light on teenager’s sleep, how it affects important aspects of teenager’s lives, and how these relationships change as teenagers get older.
