Faculty Focus - Taufik Valiante

Taufik Valiante, MD, PhD, FRCSC

Dr. Valiante graduated from the MD/PhD program at the University of Toronto in 1997, with doctoral studies completed under the supervision of Dr. Peter Carlen at Toronto Western Research Institute. Dr. Valiante then pursued an epilepsy neurosurgery fellowship at the University of Washington, Seattle, where he learned Dr Ojemann's technique of language mapping for patient's undergoing epilepsy surgery. Dr. Valiante is interested in understanding the building blocks of the human brain (neurons), and the ultimate manifestation of their collective activity (oscillations to cognition – depending on the scale of investigation). He is currently the Director of the Surgical Epilepsy Program at the Krembil Neuroscience Center, Director of the Center for Advancing Neurotechnological Innovation to Application (CRANIA), a Scientist at the Krembil Research Institute, and has a cross-appointment at the Institute of Biomaterials and Biomedical Engineering. His neurosurgical staff appointment is at the Toronto Western Hospital, and he is currently Associate Professor of Neurosurgery at the University of Toronto.
