Andrew D. Krystal, Professor Emeritus of Psychiatry and Behavioral Sciences
 Please note: Andrew has left the "CNCS: Center for nonlinear and complex systems" group at Duke University; some info here might not be up to date. My research is focused on better understanding the pathophysiology of sleep disorders and mood disorders and developing improved treatments for these conditions. My primary research tools are: electroencepahlography (EEG), polysomnography (PSG), computer signal analysis and modeling, functional magnetic resonance imaging (fMRI), and positron emission tomograophy (PET). Nearly all of my projects have been carried out with humans, however, projects are ongoing with gene knock-out models in mice, and lemurs in collaboration with the Duke Primate Center. A few representative current studies are: 1) Defining physiologic (EEG, PSG, PET, fMRI) correlates of sleep complaints and subtyping insomnia on the basis of the associated pathophysiology, 2) Studying the relationship of EEG data recorded during non-REM sleep, daytime function, and insomnia treatment response, 3) Developing new pharmacologic and non-pharmacologic treatments for insomnia, 4) Studying the relationship of natural sleep and hibernation-like phenomena (torpor), 5) Predicting depression treatment response on the basis of pre-treatment EEG and structural MRI data.
