Rsearch interests

I'm interested in three main questions. How and where are long-term memories stored in the brain? Why are memories lost during neurodegeneration such as in Alzheimer's Disease? How can traumatic memories from the past be overcome? To answer these questions, my lab focuses on the emerging field of neuroepigenetics. Over the past decade, epigenetic mechanisms in the brain have not only been shown to react to fluctuating environmental contingencies, but also to encode the cell fate of neurons and other cell types during development. With this Janus-faced property of being at once dynamic and stable, epigenetic mechanisms harbor the potential to better explain the molecular processes that govern learning, memory and memory loss. In extension, because epigenetic mechanisms are also amenable to pharmacological intervention, they might constitute a novel angle on how to counteract memory loss and resilient traumatic memories.
