Translational Neurosurgery Laboratory
Vision
The Translational Neurosurgery Laboratory's mission is to develop new neuro-technologies to modulate brain activity and unlock next-generation tools for clinicians treating patients suffering from brain diseases.
We are working at the interface of psychology, engineering, gene therapy and neurosurgery.
Our team is optimizing the following technologies to help understand and modulate neural activity:
Wireless neurophys
Optogenetics
Chemogenetics
Neurosurgery
Director
Dr. Sébastien Tremblay completed his Masters studies in psychology at Université de Montréal and his Ph.D. in neuroscience at McGill University. He went on to pursue a first fellowship at the Montreal Neurological Institute and a second one at the Perelman School of Medicine at the University of Pennsylvania. He is passionate about combining psychology, engineering, and neurosurgery to further the understanding of the brain and develop new tools to treat patients with mental disorders.
TEAM
We are currently building a new team of top scientists
(see 'Join the Lab' below)
VALUES
Scientific Rigor
Searching for the truth, whatever it might be, with the best tools available
Ecological Validity
Making sure our findings have value beyond the laboratory
Cross Disciplinarity
Problems in one discipline have often been solved in another discipline
Open Science
Collaboration over competition, for the benefit of the community
