Beth Stevens

Dr. Beth Stevens is Professor of Neurology at Harvard Medical School and researcher at Boston Children's F.M. Kirby Neurobiology Center. Her pioneering work established roles for microglia and complement-mediated synaptic pruning in neural circuit development. Current research examines how neuron-glia interactions contribute to neurodegenerative diseases, neurodevelopmental disorders, and brain aging through aberrant synaptic elimination.

Studies investigate complement cascade activation (C1q/C3), phosphatidylserine signaling, and TREM2-dependent phagocytosis. Her lab employs single-cell genomics, in vivo imaging, and human iPSC models to dissect microglial states in health/disease. Honors include a MacArthur Fellowship (2015) for revealing immune mechanisms in brain development.
