My lab investigates how neurons change in order to encode learning. Our research focuses on how, when, and why synaptic connections between neurons undergo plastic changes, and how behavioural learning is encoded by such plasticity. We study a region of the brain known as the cerebellum, which is critical for learning accurate and precisely timed movements. In addition to its role in movement learning, the cerebellum is strongly implicated in autism spectrum disorders. Using a combination of electrophysiology, behavioural analysis, molecular-genetic techniques and microscopy in mice, we aim to determine the synaptic, cellular, and circuit mechanisms of learning in the cerebellum, both in health and disease.
