Edit Profile


Research Narrative:

The major focus of my research interest lies in the field of Mind-Body Medicine. Specifically, I am interested in the evaluation of the clinical effectiveness and basic psychophysiological mechanisms underlying the practice of yoga and meditation techniques. These behavioral techniques include specific manipulations of respiratory frequency and tidal volume, maintenance of body postures and stretching exercises, and meditation, which involves relaxed control of attention in a manner that precludes ruminative thought.

I am currently conducting research studies on the treatment of primary insomnia with yoga and meditation techniques which involve both subjective and objective polysomnographic evaluation of sleep quality in randomized controlled trials as well as concurrent evaluation of psychophysiological measures including cortisol, catecholamines, melatonin and heart rate variability. I am also interested in the potential effectiveness of these techniques in insomnia secondary to other conditions such as depression, anxiety and fibromyalgia and in other sleep disorders.
