Research Profile

My investigational activities involving the peripheral nervous system are mainly located at the neuromuscular junction (NMJ). Together with Chris Gomez at the University of Minnesota and Ricardo Maselli at the University of California, Davis, I analyze the morphologic changes that accompany pathology at the NMJ. We study transgenic animal models (Gomez) and patients with congenital myasthenic syndromes (Maselli). Maselli analyzes in-vitro physiology of individual junctions; I analyze the morphologic changes that appear with various genetic abnormalities in both axon termini and post-synaptic component of the NMJ. I also have collaborated with Elaine Fuchs' lab, helping them with the neuropathologic analysis of their BPAG-deficient animals-which develop a pure sensory nerve degeneration.
