Lab Overview Heading link

Our research focuses on the roles of connexins, or gap junction proteins, in myelinating glia of the central and peripheral nervous systems. Our work utilizes cutting edge techniques in genomics, proteomics, cell biology and electrophysiology, and is yielding exciting insights into a number of human diseases. We have ongoing research projects studying the role of connexins in X-linked Charcot-Marie- Tooth disease (an inherited disease affecting brain and peripheral nerves, Pelizaeus- Merzbacher like disease, PMLD (a devastating brain disease) and Multiple sclerosis. More detailed descriptions of our ongoing research projects are available here. Our work has been funded by grants from the National Institutes of Health, the Muscular Dystrophy Association and the National Multiple Sclerosis Society.
