In the Sam Doesburg Lab at SickKids, I helped develop novel methods to better identify epileptogenic areas of the brain and distinguish it from healthy eloquent cortex.

In the George Ibrahim Lab at SickKids Hospital, I am currently studying the effects of epileptic activity on brain networks both during and between seizures, and developing new treatments to rescue critical network function.

Brain networks in autism, ADHD, PTSD, and concussion

In the the Margot Taylor Lab at SickKids Hospital, we studied higher-order cognitive processes such as social cognition, emotional face processing, working memory, and cognitive flexibility in children and adolescents, through to older adulthood.
