I am an Assistant Professor at Boston University in the Department of Psychological and Brain Sciences. The mission of my lab’s research is to artificially modulate memories to reverse and prevent psychiatric disease-like states, such as depression- and anxiety-related phenotypes. My previous work identified a defined set of cells active during various memory formation, genetically engineered these cells to respond to light, and optically activated or inhibited these cells while measuring the associated behavioral outputs. These projects focused on mapping out which brain regions were necessary and/or sufficient for memory recall, artificially creating false memories in the rodent brain, modulating the emotional strength associated with specific memories, and leveraging these aforementioned manipulations to reverse depression-like phenotypes. My current projects aim to study the brain-wide cellular mechanisms that confer therapeutic or deleterious value to artificially activated positive and negative memories in mice.
