Research Interests
Our research laboratory is broadly interested in both normal and aberrant brain development, and our long-term goal is to identify novel therapeutic strategies to mitigate the impact of specific developmental brain disorders. Current research is focused on the prefrontal cortex and hippocampus, two regions of the brain that are responsible for higher-order cognitive processes including learning, memory and attention. Alterations to the prefrontal cortex and hippocampus are observed in a number of neurodevelopmental disorders such as Attention Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorders (ASD), and also following developmental exposure to drugs such as nicotine and alcohol. Work in our laboratory employs an integrative experimental approach utilizing modern molecular, electrophysiological and behavioural techniques to identify mechanisms underlying the development and function of the prefrontal cortex and hippocampus, and to understand how these processes may be altered within specific developmental brain disorders.
