Research Interests

Neuronal activity induces molecular and genetic mechanisms which underlie synaptic plasticity and the establishment and maintenance of functional neural networks. Calcium signaling to the nucleus, through activation of both NMDA Receptors and voltage gated calcium channels, is critical for these long lasting changes. My research focuses on understanding how information from neuronal activity is conveyed to the nucleus by calcium dependent pathways. This will shed light on how neural networks develop, and how they are perturbed in neuropsychiatric disease.
