Dr. Andres Lozano is a distinguished neuroscientist of international reputation. His research is focused on developing novel surgical treatments for neurological and psychiatric disorders particularly for Parkinson’s disease and depression. Dr. Lozano obtained his MD degree from the University of Ottawa and his PhD in Neurobiology and neurosurgical training from McGill University. He was appointed to the Department of Surgery at the University of Toronto in 1991 and was named full Professor in 1999. He is currently Professor and RR Tasker Chair in Functional Neurosurgery and holds a Tier 1 Canada Research Chair in Neuroscience. Dr. Lozano’s work has appeared in over 300 peer reviewed publications and he is highly cited ranking in the top 5 in the world in the fields of both Deep Brain Stimulation and Parkinson’s disease. He is the editor in chief of the Textbook of Stereotactic and Functional Neurosurgery and has trained approximately 50 neurosurgical fellows and PhD students. He has served on the board and executive of several international organizations and is Past-President of the World Society for Stereotactic and Functional Neurosurgery. Dr. Lozano has received a number of awards including the Gold Medal of the Royal College of Physicians and Surgeons of Canada, the Penfield Award, the Order of Merit of Spain and the Jonas Salk Award and has been elected a fellow of the Royal Society of Canada. Dr. Lozano’s research focus is on novel surgical approaches to treat Parkinson’s disease, depression and Alzheimer’s disease. His team uses brain imaging, electrophysiology and surgical techniques. Their work in humans is complemented by laboratory work involving cell death in Parkinson’s disease, effects of stimulation on hippocampal neurogenesis and animal models of deep brain stimulation.
