Our lab is generally interested in how the nervous system is assembled and maintained. More specifically, we're investigating the role of glial cells in: 1) formation of the nervous system early in development, and 2) nervous system preservation during disease and injury.

Formation of a functional nervous system requires the coordinated interactions of several types of cells derived from distinct precursor populations. These cells must often migrate great distances, identify each other and coordinate their differentiation. This ensures that information can be passed between the central nervous system (CNS) and peripheral nervous system (PNS) targets via peripheral nerves. Investigating the cellular and molecular mechanisms that mediate motor nerve formation will provide important insights into the developmental programs that assemble and maintain functional nervous systems.
The long-term goal of the work in the lab is to understand the development of spinal motor nerve components and how glial-glial interactions result in coordinated differentiation, myelination, maintenance and regeneration of nerves. To begin to address these developmental paradigms, we use zebrafish as a model system because it uniquely provides the opportunity to combine in vivo, time-lapse imaging with genetics.
Recently, we have begun using mice to complement our zebrafish studies and are currently very interested in the glial-glial interactions that occur across nervous system transition zones during normal development and under disease condictions.
