Research Interests

We study the mechanisms underlying the processes of learning and memory, at the molecular, cellular and systems level. Current projects focus on the NMDA receptor and the immediate-early gene Arc, which play essential roles in learning and memory consolidation, respectively. We have shown that efficient Arc translation requires coincident activation of the NMDA receptor and receptors associated with fear/reward pathways, suggesting that Arc mediates a role for emotion in memory consolidation. Our localization of Arc protein to the nucleus, and its association PML bodies, suggests that Arc mediates formation of long term memories through epigenetic regulation of gene expression. A second project investigates how information is processed, encoded and stored in networks formed by neurons growing in vitro, using a combination of optogenetics and multi-electrode array recording techniques. These experiments have demonstrated that cultured neuronal networks have fading and hidden memory processes that are similar to those observed in vivo, and thereforeprovide a novel platform for investigating the molecular and physiological basis of disorders in memory, cognition, and perception. These projects are supported by an in silico drug design program which identifies small molecules with efficacy at therapeutic targets identified by our research program.
