My main interest is the pathogenesis of demyelinating diseases, particularly those caused by mutations in the genes that encode the gap junction proteins Cx32 and Cx47. My current projects in my scientific laboratory relate to (1) the role of Cx32 in the pathogenesis of inherited demyelinating neuropathy, (2) how gap junctions between astrocytes and oligodendrocytes affect the structure/function of CNS myelin, (3) how the myelin sheath organizes the structure of the axon, and (4) animal models of inherited neuropathies. In the clinic, I also participate in a large effort in finding new genetic causes of inherited neuropathies.
My clinical work is focused on people who are known (or are suspected to have) a peripheral neuropathy. To diagnose neuropathy, I perform a comprehensive history and focused neurological examination, typically including clinical neurophysiology ("EMG"). This assessment enables me classify someone's neuropathy (examples - diabetic, inherited, chronic inflammatory demyelinating polyneuropathy (CIDP), Guillain-Barre syndrome (GBS), vasculitic, toxic, idiopathic, "small fiber"), and guides further testing. Establishing the correct diagnosis can lead to treatments for neuropathies caused by compression, inflammation, vitamin deficiencies, amyloid, or toxins. In addition, I work with people to reduce their neuropathic pain.
