Professor of Neurology; Associate Dean for Academic Affairs; Director, LSUHSC-S Sleep Disorders Center; Director, Sleep Fellowship Frogram; Editorial Board Member, "Journal of Sleep Medicine"; Member of the AASM Presidential Committee on Sleep Education and Medical Schools; Chairman of the Academic Affairs Committee at LSUHSC-S.
Research Interests Sleep Disorders, Obstructive Sleep Apnea (OSA): especially in relation to oxygen desaturation measurements and computer-based programs to record and quantitate severity of desaturation and correlation of symptoms and signs with levels of hypoxemia and with severity of sleep fragmentation. The New Manual for Scoring Polysomnography has provided opportunities to validate measurements of movement disorders in sleep (excessive fragmentary myoclonus, restless leg syndrome, periodic limb movements in sleep). Quantitative Analysis of Electroencephalogram and computer-based decision making for evaluation of human sensitivity to external electromagnetic fields and study of neural systems involved in transduction of these fields in the human brain. Teaching and Education: Both for medical students and for patients’ education. Influences of low literacy on patient education. Use of standardized patients in medical student and house staff education.
Specialized Techniques/Procedures Nocturnal oxygen desaturation measurements Saturation impairment time All types of polysomnography EEG Generation, characterization and application of low-frequency electromagnetic fields to human subjects Standardized patients in education Excessive fragmentary myoclonus Restless leg syndrome Periodic limb movements in sleep
