The Team


Principle Investigator 

Taufik A. Valiante

Taufik Valiante completed his residency in the Neurosurgery Training Program at the University of Toronto in 2002, and an Epilepsy Surgery Fellowship at the University of Washington, Seattle, under the mentorship of Dr. George Ojemann in 2003. In 2007 he established a state of the art five-bed Epilepsy Monitoring Unit at the Toronto Western Hospital, significantly increasing surgical services to those with medically refractory epilepsy throughout the Province of Ontario. Through his involvement with professional and not-for profit epilepsy organizations, he is a strident advocate for the standardization of epilepsy care.

He is currently the Director of the Surgical Epilepsy Program at the Krembil Neuroscience Center, 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.




Lab Members



Victoria Barkley

Research Technical Assistant

Victoria is a Research Technical Assistant serves as liaison between Dr. Valiante's trainees, collaborators, EMU staffclinicians and research candidates. Specifically, she works with patients who are eligible to participate in electrocorticographic  (ECoG) studies. She is also responsible for clinical data collection and post-operative reconstructions.









Fellows and Associates


David Groppe

David is a clinical neuroscientist/data scientist trying to develop ways to mine the vast amounts of data acquired from epilepsy surgery candidates to improve epilepsy therapies and our understanding of the functional organization of the human brain.







Homeira Moradi 

 Scientific Associate

Homeira invistigates the impact of intrinsic cellular properties of human cortical neurons on network activity in cortical slices obtained from neurosurgical procedures. Her work focuses on the role of electrophysiological properties of single neurons in generating electrical oscillations in the brain and using these data to build a human cell model through a collaboration with Dr. Francis Skinner. 

To perform these experiments, she use in vivo and in vitro electrophysiology, including patch clamp techniques and local field potential recordings. In addition, she uses 3D image reconstruction of a neurons using immunohistochemistry and CLARITY.
