Dr Karyn O'Keeffe PhD

Senior Lecturer

Doctoral Supervisor
School of Health Sciences

Dr Karyn O’Keeffe began her career in sleep research and medicine as a Clinical Physiologist at WellSleep, Sleep Investigation Centre, University of Otago Wellington, where she worked for 10 years and gained first-hand experience of shift work.  She began to transition to the Sleep/Wake Research Centre in 2006 and has been based at the Centre full-time since 2012.

Karyn has been involved in both basic and applied sleep and circadian research, investigating sleep at moderate altitude, treatment provision for sleep disorders, the interaction between ventilatory and cardiac timing during sleep, and fatigue risk management for various industry groups.  Her current work primarily focusses on the management of shift work and fatigue in health care settings, most recently nursing (www.safernursing24-7.co.nz).

Dr Karyn O’Keeffe is a Senior Lecturer at the Sleep/Wake Research Centre, School of Health Sciences.  She is a sleep physiologist with considerable clinical experience in monitoring sleep and managing sleep disorders.  Karyn has broad research interests but is particularly passionate about exploring the impacts of shift work and improving the management of the risks associated with shift work and fatigue for healthcare professionals, as well as improving sleep health in the general population.
