My long-term research interest is to identify genetic pathways that control the development and function of the nervous system in the context of developing strategies to treat neurodegenerative disorders. By positionally cloning genes responsible for spontaneously occurring neurological mouse mutations, my laboratory identified Ubiquitin specific protease 14 and components of the ubiquitin proteasome pathway as critical regulators of neuronal signaling during development. In addition to investigating the mechanisms of ubiquitin homeostasis in regulating synaptic formation and function, my current research uses conditional inactivation of genes in mice and primary cell culture to study the essential roles of endosomal sorting in Schwann cells during peripheral nerve myelination.
