Ann Hermundstad

Ann Hermundstad

Ann Hermundstad received a PhD in Physics from the University of California in Santa Barbara (UCSB). She was a postdoc in the group at Penn, working on problems in theoretical and computational neuroscience, focusing both on specific sensory pathways and integrated whole-brain studies. She employed a range of theoretical, computational, and data-driven techniques to probe how different cellular architectures support and constrain emergent biological function. Her work touched on a broad set of related questions that elucidate how resources are distributed across populations of cells, how local interactions shape information flow across the population, and how the structure of interactions adapts over time and in response to stimulus variations. Current projects relate to population coding in the retina, visual perception of higher-order spatial statistics, olfactory processing, and structure-function relationships in the human brain. Ann is currently a Group Leader at the Janelia Research Campus of the Howard Hughes Medical Institute.
