My laboratory is focused on defining and analyzing the mechanisms that regulate vertebrate brain morphogenesis during development. In almost all organs, generation of three dimensional structures requires bending of an epithelial sheet. After neural tube formation and specification of different brain regions, the developing vertebrate brain bends multiple times to subdivide regions and pack itself into the skull. Embryonic brain shape is highly conserved across vertebrate species indicating the unique and essential requirement of a shape-function relationship in early brain development. This research is important because abnormal brain morphogenesis can result in a range of disorders including neural tube defects, hydrocephalus, and mental health disorders such as autism and schizophrenia.

Our lab applies genetic, developmental, molecular, and cell biological approaches to study brain morphogenesis in zebrafish (Danio rerio) embryos. The challenge is to determine the mechanisms of brain morphogenesis within a live organism. Zebrafish biology provides a robust in vivo model for sophisticated and feasible developmental studies. Zebrafish have rapid development, short generation time, and transparent embryos allowing for in vivo live imaging.

Specific Areas of Interest:
  1. Determining the mechanisms for how non-muscle myosin II regulates cell shortening during the formation of the midbrain-hindbrain boundary constriction.
  2. Discovery and characterization of the role for unconventional myosins in brain morphogenesis and disease.
  3. Analysis of the role of molecular motors in neurite outgrowth during brain development.
