About
I am currently an NINDS K00 postdoctoral research fellow in the Datta Lab at Harvard Medical School, where I leverage deep learning techniques, molecular biology, and systems neuroscience to investigate how steroid hormones modulate neural circuits.
Previously, I earned my Ph.D. in Molecular, Cellular, and Developmental Biology at UC Santa Barbara, where I was advised by Dr. Michael Goard. My doctoral research employed in vivo two-photon microscopy to investigate how endogenous hormone cycles drive changes in spatial representations and neuronal morphology in the hippocampus.

Research
-
Endocrine-modulated hippocampal plasticity
The hippocampus is densely populated with estrogen receptors, and ex vivo work has shown that the spines on apical CA1 pyramidal cell dendrites change with estrogen. What does that mean for function across the estrous cycle and pregnancy? Longitudinal in vivo imaging of dendritic spines in densely sampled mice, paired with analysis of spatial representations, shows that both neuronal morphology and spatial navigation are modulated by sex steroid hormone fluctuations.

Automated classification of estrous cycle stage
Estrous phase is identified by vaginal lavage and cytology, but manual classification is error-prone, and fast, accurate staging is critical for neuroendocrine research. EstrousNet is a deep learning pipeline for unbiased classification. To mimic human classification more closely, it fits test images to an archetypal estrous cycle, which avoids common confusion errors. Its classifications surpass expert accuracy and speed.

Neural basis of spontaneous behavior
In my current role I am using single-cell RNA sequencing to investigate how steroid hormones modulate sensory representations. By pinpointing the molecular changes in olfactory sensory neurons driven by steroids, we can identify cortical areas that are longitudinally remodeled by these hormones.
