John N. Campbell, Ph.D.
Assistant Professor, Department of Biology, University of Virginia
Affiliate Faculty, Department of Neuroscience, UVA School of Medicine
Our lab investigates the complex and interconnected neural processes behind appetite, digestion, and metabolism. We use single-cell genomics to identify neuronal subtypes in key brain regions, then apply genetic tools to map each neuron type's synaptic circuitry and monitor and manipulate their activity in vivo, revealing their physiological role. A current focus is the parasympathetic neuron populations of the hindbrain that control different functions of the digestive system, including gastric motility and insulin secretion.
John received his B.S. in Biological Psychology from The College of William & Mary, a Ph.D. in Neuroscience from Virginia Commonwealth University’s School of Medicine, and completed a postdoctoral research fellowship with Brad Lowell's lab at Harvard Medical School and Beth Israel Deaconess Medical Center. He previously held the position of Instructor of Medicine, Harvard Medical School.
