About me

I am a medical doctor specialising in psychiatry with a special interest in
sleep, depression and emotion.
I am a postdoctoral fellow working in Viktor Kaldo's research group within
CPF.

Research

My current research focuses on understanding links between insomnia and
depression using epidemiological brain imaging data, cognitive behavioural
therapy for insomnia and experimental sleep studies. I also study how
behavioural sleep treatments can be disseminated to patients in psychiatry.
During my PhD I investigated the effects of acute sleep deprivation on brain
function, with a focus on emotion using functional magnetic resonance
imaging. I also investigated the role of low-grade inflammation as a
mechanism behind non-specific symptoms such as fatigue and depressive
symptoms in patients with severe allergy using positron emission tomography.
