The incidence and complexity of mental illnesses and cognitive impairments associated with ageing and Alzheimer’s disease underscores the need to develop novel treatments. Our mission is to generate fundamental insights into the contributions of circuit- and plasticity mechanisms in the dentate gyrus (DG)-CA3 circuit in hippocampal memory processing and modulation of mood. By integrating cellular, circuit, systems and behavioral interrogation of DG-CA3 circuits, inhibitory microcircuits and adult hippocampal neurogenesis, we aspire to rejuvenate and re-engineer hippocampal circuitry to optimize circuit performance and memory processing. We predict that this strategy will edify strategies to treat PTSD, Alzheimer’s disease, social memory disorders and age-related cognitive decline.

Our laboratory is embedded in the Center for Regenerative Medicine at Massachusetts General Hospital and is part of a matrix that includes the Harvard Stem Cell Institute and the Department of Psychiatry at MGH.
We are committed to mentoring and training the next generation of scientists to understand the workings of the brain and tackle brain disorders. The laboratory hosts individuals at all stages of their careers and I aspire to continuously evolve as a mentor.
