My main area of research and clinical practice is insomnia and sleep disorders in adults. I've worked in the field of Behavioural Sleep Medicine (aka sleep psychology) since 2002.

After completing my masters and PhD at UWA in 2001, I worked as a postdoctoral research fellow at Oxford University. During this time I worked on a trial of cognitive therapy for Insomnia and projects investigating and measuring insomnia maintaining processes.

Since moving back to Perth I've worked as a clinical psychologist in hospital and private practice settings. I've established Jeffery&Ree clinical psychologists and Sleep Matters where I provide sleep psychology interventions and conduct training on evidence-based insomnia treatment.

My research involvement has continued, via supervision of postgraduate research projects at UWA, Murdoch and Curtin universities. Projects have included investigating the effectiveness of CBT-Insomnia in the general population, psychiatric population, psychotic illness, and the over 65s. The role of Mindfulness as an adjunct to CBT-I has also been an interest, along with the continued investigation of process variables that affect treatment outcome. An ongoing project is investigating the impact of medicinal cannabis on insomnia symptoms.

My senior lecturer role at UWA commenced in April 2019 and I'm very much looking forward to further teaching and research the field of behavioural sleep medicine.
