I obtained my PhDs (1) Neurophysiology and 2) Clinical neurology and human behavior) at the University of Bordeaux, France working on rodents and non-primates models of Huntington’s and Parkinson’s Diseases. From 1986, I pursued my training at Johns Hopkins School of Medicine (Baltimore, USA) in the laboratory of Dr. Delong and got my first exposure to brain imaging methodologies in Louis Sokoloff’s Laboratory of Cerebral Metabolism at the NIMH. In 1993 I joined the UBC/TRIUMF PET program. I am currently full Professor in the Department of Medicine (Division of Neurology) and am a member of both the Brain Research Center and the Pacific Parkinson Research Center. I also maintain a close collaboration with investigators in the University of Aarhus where I hold an adjunct appointment.
