Dr. El Beheiry is an Assistant Professor of Anesthesia at the University of Toronto. He obtained his Anesthesia FRCP specialty certificate in Anesthesia in 1994. He had a PhD from the Department of Pharmacology and Therapeutics at the University of British Columbia, Vancouver, British Columbia, Canada. He also spent a year as a Fellow in Clinical Pharmacology at the University of British Columbia, Vancouver, British Columbia, Canada. He is trained as a neuroanethesiologist and had Clinical Fellowship training in Neuroanesthesia at the University of Toronto, Toronto, Ontario, Canada. He practiced at the University Health Network, The Toronto Western Hospital, Toronto, Ontario, Canada from 1995 to 2007 and then he moved to the Trillium Health Partners, Mississauga Hospital and Queensway Health Centre since 2008. His interests are currently focused on clinical neuroanesthesia particularly EEG signal processing in collaboration with the Institute for Biomaterials and Biomedical Engineering, the University of Toronto.
