Areas of Clinical Interest

Outpatient consultation and hospital sleep medicine, obstructive sleep apnea, central sleep apnea, treatment adherence issues associated with positive airway pressure therapy, sleep related hypoventilation, obesity hypoventilation syndrome, circadian rhythm disorders, insomnia, hypersomnia, narcolepsy, restless leg syndrome, periodic limb movement disorder, and parasomnias (sleep walking, sleep-related eating disorder, REM behavior disorder, etc).
