Arne Lowden (3rd Term)

Arne Lowden is Associate Professor, is currently working as a sleep and stress researcher at the Stress Research Institute at Stockholm University in Sweden and at Karolinska Institute. He has studied adaptation to work in shiftwork and adolescence, evaluated self-selected workhours, done experimental studies on night eating and sleep. Lately he studies effects on sleep & recuperation using bright light in working life. He is on the Editorial Board of the Scandinavian Journal of Work, Environment & Health and the Sleep Science Journal.

Sampsa Puttonen (3rd Term)

Associate professor Sampsa Puttonen is working as a senior researcher at the Finnish Institute of Occupational Health. He is also a principal investigator at the University of Helsinki, FI. He has published about 80 peer-reviewed publications that have focused on psychosocial stress, recovery, sleep, and working times, especially shift work. In addition to working in large-scale epidemiological cohorts, he has broad expertise of laboratory and field studies where his interest has been on disentangling the mechanisms (both individual and organizational) underlying the associations between working times and health. Recently his work has focused upon on applied interventional studies, where the aim has been on changing working time arrangements.

Imelda Wong (3rd Term)

Imelda Wong completed her PhD in the School of Population and Public Health at the University of British Columbia, Canada. Her dissertation focused on the effects of shift work and stress on cardiovascular disease by using an interdisciplinary approach combining health psychology, epidemiology, exercise physiology and occupational hygiene. She completed her post-doctoral fellowship at the Institute for Work and Health, where she used national survey data to continue studying health risks associated with shift work. She is currently a Research Fellow with the US National Institute for Occupational Safety and Health and is expanding her work to include fatigue, work scheduling and risk for motor vehicle crashes. Current projects also include developing and evaluating Fatigue Risk Management systems.

Thomas Kantermann (3rd Term)

Thomas Kantermann studied Biology and Psychology at the University of Bielefeld (DE) and after obtaining his diploma he worked on human brain development at the University of Rostock (DE). He later obtained his PhD at the Ludwig-Maximilians-University Munich (DE) in the field of human chronobiology focussing on health in shift workers and the impact of daylight saving time on sleep and circadian rhythms. He did his postdoc at the University of Surrey (UK) studying cardiovascular risk in Belgian shift-workers. After half a year at the Department for Sleep Medicine at the Charité in Berlin (DE), he joined the Chonobiology Unit at the Groningen Institute for Evolutionary Life Sciences (GELIFES) at the University of Groningen (NL) in the Dutch research consortium OnTime – How to fix a (broken) circadian clock. Thomas is founding member of the International Society for Working Time, founding member of the Daylight Academy (Velux Foundation, CH), and both founding member and scientific director of the urban science project ChronoCity Bad Kissingen (DE). He also is board member of the European COST action Loss of Night Network. In 2016, he finished his Habilitation at the Ludwig-Maximilians-University Munich (DE) and obtained the Venia legendi in Medical Psychology. In 2016 he started his own company 'SynOpus' (located in Germany). Since 2018, Thomas is Professor for health psychology at the University of Applied Sciences for Economics and Management (FOM).

Greg Roach (2nd Term)


Greg Roach is an Associate Professor at the Appleton Institute for Behavioural Science, CQUniversity.  Greg has conducted a range of projects in laboratory-, simulator-, and field-based settings.  This research is focussed on the impact of irregular work schedules on the sleep/wake behaviour of shiftworkers; the development of technologies and systems to manage the fatigue risk associated with shiftwork; the mechanisms that control the human sleep/wake system; the effectiveness of split sleep/work schedules for employees in industries that require long hours of duty on consecutive days; the impact of sleep restriction and body clock disruption on a predisposition to develop chronic illnesses such as obesity, diabetes, and cardiovascular disease; and the relationships between training load, sleep patterns, and sports performance in world-class athletes.
