Guidance cues

Guidance cues are conserved proteins that are required for neurodevelopment. Interestingly, they are still expressed in the adult brain, and play key roles in synaptic transmission underlying learning and memory formation.

Synaptic plasticity

Learning and memory formation requires the constant reorganization of synapses, highly-specialized sites of chemical and electrical communication in the brain. This involves not only molecular shuffling but also structural changes at the level of individual neurons.

Spatial memory

Changes in how brain cells communicate with one another can impact network function that underlies memory formation. These synaptic alterations can result in different spatial representations, called cognitive maps, but how guidance cues impact these maps remains unclear.

Autism Spectrum Disorder

Understanding the molecular mechanisms underlying synaptic dysfunction in autism spectrum disorder (ASD), a heterogeneous behaviourally-defined neurodevelopmental disorder that is characterized by repetitive behaviours, impaired social interaction, and perturbation of communication, is a key goal of my research program. ASD patients also show impaired memory consolidation, suggesting dysfunction in cellular and molecular mechanisms underlying synaptic transmission and plasticity. Interestingly, a number of genes required for guidance cue signaling have been linked to neurodevelopmental pathophysiologies associated with abnormal memory function, including ASD and Fragile X syndrome. Our research program will evaluate the role of guidance cues in synaptic transmission, and explore how this group of proteins may contribute to pervasive developmental disorders such as ASD.
