Summary of Research

I aim to develop generative connectivity models that are constrained using prior knowledge such as spatial features and functional types. Deviations from these random models will reveal structural motifs of interest across multiple connectomes. In the Litwin-Kumar lab, I am developing such pipelines and applying them to multiple partial connectomes of the fly mushroom body (center for olfactory discrimination and learning) to detect structure in neuronal circuits involved in odor representation. When these comparative methods are fully developed, they will enable us to probe
structural differences in individuals across different age groups, sexes, and experiential history, link brain structure to function, and elucidate features contributing to neuropathologies.
