Research

This research team applies the tools of molecular biology to uncover the mechanisms underlying how the brain adapts and responds when memories are formed. As aging, brain trauma and neurological diseases result in deterioration of memories and have catastrophic affects both to the individual affected and society as a whole, it is important to understand the molecular steps involved in the maintenance of memories and identify how these are perturbed in disease.
