Gregory Potter, Ph.D.
Research Assistant Professor

Greg studied BioEngineering at UC Berkeley before obtaining a PhD in Neuroscience from Johns Hopkins University School of Medicine. He did postdoctoral work at UCSF studying interneuron and oligodendrocyte differentiation. He is interested in understanding how oligodendrocytes initiate, direct, and maintain axonal myelination, and applying this knowledge to improve treatment of glial-based neurological diseases such as multiple sclerosis and leukodystrophies.
