Faculty Focus - Andres Lozano


Andres Lozano Andres M. Lozano, MD, PhD, FRCSC, FRSC, FCAHS

Dr. Lozano was born in Sevilla, Spain and moved with his family to Ottawa at a young age. He obtained his MD degree from the University of Ottawa and his PhD in Neurobiology and neurosurgical training from McGill University. He received postdoctoral training in movement disorders at Queen Square, London, UK and in cell and molecular biology in Toronto. He was appointed to the University of Toronto in 1991, and in 1999 he became the youngest individual to be appointed Full Professor in the Department of Surgery. In 2014 he was appointed to the rank of University Professor, the highest and most prestigious academic rank at the University of Toronto. He is currently Chairman of the Division of Neurosurgery at the University of Toronto and holds with it, the Dan Family Chair in Neurosurgery. He also holds the RR Tasker Chair in Functional Neurosurgery at University Health Network and a Tier 1 Canada Research Chair in Neuroscience.

Dr. Lozano has an active laboratory dedicated to the study of neurodegeneration and functional neurosurgery. He has published over 450 manuscripts, 90 chapters and edited 5 books. He has the unique distinction of being named the most highly cited neurosurgeon in the world (Thompson Reuters, 2002-2012). Dr. Lozano has been an invited speaker or visiting professor throughout the world, delivering over 500 lectures including 45 named lectures such as the Penfield, Marsden, Leksell, Feindel, Ojemann, Hunt-Wilson, Winn, Salk and Olivecrona lectures. He has served on the board and executive of several international organizations, including the founding scientific advisory board of the Michael J. Fox Foundation and the Weston Brain Institute, and has been President of both the American and World Society for Stereotactic and Functional Neurosurgery. He is editor-in-chief of the Textbook of Stereotactic and Functional Neurosurgery and currently serves on the international editorial board of 18 journals. Dr. Lozano is married to Marie and they have two sons, Alexander and Christopher.

Areas of Interest and Expertise

Dr. Lozano is best known for electrical recording and stimulation mapping of hitherto unexamined brain areas and for the identification and testing of novel therapeutic targets for deep brain stimulation (DBS). He and his team have pioneered the “first in man” applications of DBS in dystonia, Huntington’s, depression, anorexia and Alzheimer’s disease and locomotor brainstem areas in Parkinson’s disease. His recent work in experimental animals has shown that DBS can drive neurogenesis and enhance memory function. He is currently leading a large multicenter trial of DBS for Alzheimer’s disease. Dr. Lozano is particularly proud of the residents in the neurosurgery training program in Toronto and the more than 60 functional neurosurgery fellows that have trained with him and gone on to become leaders in their field.
