Research Interests

My major research interest is in understanding sleep architecture features that contribute to symptoms related to non-refreshing sleep, from both “trait” (inter-individual differences) and “state” (night-to-night variation in those with fluctuating symptoms) perspectives.  The approach involves quantitative analysis and modeling of sleep stage transition dynamics, using standard scoring rules as well as novel “state” designations (for example, based on cardiopulmonary metrics).  Because we and others have shown that the routine 1-night clinical sleep study contains insufficient data for robust architecture/transition analysis, I am focusing on long-term unobtrusive sleep monitoring in the home setting. 

The major clinical focus is currently on insomnia, with particular emphasis on sleep state misperception.  However, the exciting aspect to these home monitoring systems is their easy translation to neurological and psychiatric populations in which sleep disturbance is hypothesized to be related to the disease pathogenesis or response to treatment. 

Active collaborations continue with Dr Robert Thomas (BIDMC) on cardiopulmonary coupling methods, Dr Elizabeth Klerman (BWH) on computational modeling of sleep architecture, and Dr Syd Cash (MGH) on invasive electrophysiology of human sleep in epilepsy patients undergoing surgical evaluation. 

Finally, I have interests in decision theory applied to Neurological populations, including those with sleep disorders (Bayesian approaches, Markov decision trees, and quantifying the impact of uncertainty of input parameters used in these strategies).
