Full Professor, Faculty of Dentistry, Université de Montréal Dean, Faculty of Dentistry, Université de Montréal Director of the Pain, Sleep and Traumatology Laboratory Holder of the Canada Research Chair on Pain, Sleep and Traumatic injuries 514-343-6005 gilles.lavigne(at)umontreal.ca Education: Ph.D. in Dentistry (University of Toronto) Certificate in Oral Medicine (Georgetown University) M.Sc. in Neurological Sciences (Université de Montréal) D.M.D. (Université de Montréal) Research Interests: Clinical neurophysiology of sleep and pain, as well as specific disorders including sleep bruxism, sleep apnea, and periodic leg movements during sleep. Psychophysiology of vigilance and pain. Placebo effects of analgesia, and the influence of analgesia (morphine and other opiods on sleep). Orofacial pain and oral medicine. Methodologies: Polysomnography, spectral analysis of cardiac variability and cerebral activity, morphology of respiratory waves in relation to oromandibular and nasal structure, and psychophysiological pain evaluations using quatitative methods.
