Area of Interest:

My research seeks to understand the neural circuit basis of memory formation. The memory formation process is not a single-stage process that stores sensory inputs in one location. Rather, it is mediated by multi-stage processes (i.e. encoding and consolidation) that involve communications between different brain regions. Encoding is described as forming quick temporary memories in the hippocampus, which inherits information from the neocortex that initially receives sensory inputs. Consolidation refers to the process of forming long-term memories in the neocortex, which receives recently encoded hippocampal information. As these two memory stages operate in mutually exclusive modes (i.e. encoding during waking and consolidation during sleep) and are differentially modulated by external signals, studying these distinct memory formation processes is crucial in order to fully understand the mechanism of memory formation. Using a variety of in vitro and in vivo recording approaches such as fiber photometry, electrophysiology, and miniature microscopy, I aim to investigate neural circuits responsible for memory consolidation and how these circuits are altered in disrupted metabolism and dementia. In addition, I use optogenetics and chemogenetics along with behavioral testing to assess the functionality of a specific memory circuit.
