Dr. Anne Hart obtained her Ph.D. in Neuroscience at UCLA with Dr. S.L. Zipursky working on cell fate specification in the Drosophila eye. She undertook her post-doctoral training in C. elegans genetics with Dr. Josh Kaplan in the Department of Molecular Biology at Massachusetts General Hospital. Dr. Hart joined the Center for Cancer Research at the Massachusetts General Hospital and the Harvard Medical School Department of Pathology as an assistant professor and taught numerous classes in genetics and neuroscience. She moved to the Department of Neuroscience at Brown University in the fall of 2009. She has served as faculty in neuroscience courses at the Marine Biological Laboratories and the Okinawa Institute of Sicence and Technology. Her research focuses on the molecular and cellular mechanisms underlying neurological disease, sensory signaling, sleep, and adaptation to environmental stress.

Anne Hart is a neurobiologist who uses genetic and molecular approaches in the small nematode C. elegans to understand the conserved mechanisms underlying neurodegenerative disease and nervous system function. She focuses on delineating cellular and molecular pathways pertinent to Spinal Muscular Atrophy (SMA) and other motor neuon diseases. Dr. Hart also studies the genetic and molecular mechanisms regulating sleep, how animals respond to sensory stimuli, and stress/aging.
Dr. Hart's research has focused primarily on neurodegenerative disease and neuronal signaling using the C. elegans nervous system. Currently, she and her lab members are working on 1) Spinal Muscular Atrophy and on 2) Notch signaling in behavior, sleep, and stress response.
Dr. Hart uses forward and reverse genetic techniques to identify pathways critical for neurodegenerative disease and has established the utility of C. elegans for modeling these human disorders. In the last few years, her laboratory has primarily focused on delineating the cellular and molecular pathways that play critical roles in Spinal Muscular Atrophy (SMA) as part of a collaborative effort with Drs. S. Artavanis-Tsakonas and D. van Vactor. Having multiple C. elegans models of neurodegenerative disease on hand allows both intellectual and practical synergy in characterizing relevant pathological pathways. Dr. Hart's group is currently developing C. elegans models of ALS.
Dr. Hart and her laboratory also undertake behavioral, molecular, and genetic studies to understand how animals respond to changes in the environment. This resulted in the identification of a new family of conserved Notch co-ligands in C. elegans. Current research examines 1) the role of these Notch co-ligands in cell fate specification during development, 2) the role of the Notch pathway in stress resistance/longevity, and 3) the targets of Notch signaling in adult behavior and sleep. Dr. Hart's group originally identified OSM-11 as a protein required for normal adult behavior and they are now addressing neuronal roles for the Notch signaling pathway. The role of Notch signaling in the adult nervous system is poorly understood in any system.
