The fundamental question addressed in my group is: how is memory stored as information in the brain? Recent studies have shown that spatial memories are encoded as sparse populations of cells that are activated during learning and are necessary for the retrieval of specific memories. We refer to these cells as "memory engram cells" and the focus of my group is to understand how engram cells are able to store specific memories as information. To address this question we study memory encoding, storage, and retrieval in the mouse. We employ interdisciplinary experimental approaches, including behavioural neuroscience, optogenetics, engram labeling technology, electrophysiology, calcium imaging, and molecular genetics.
