Current Research

My research laboratory uses zebrafish to study cell-to-cell junctional complexes (cadherin adhesion) and their role in developmental processes.  Cadherins are transmembrane proteins that mediate cell-to-cell adhesion within the adherens junctions, and cadherins regulate embryonic development by controling differentiation mechanisms, polarized cell behaviors (e. g., cell migration) and tissue organization.  We examine the functions of individual zebrafish cadherins during specific morphgenesis and differentiation events, particularly during eye and ear morphogenesis.

My laboratory also uses the zebrafish to model fetal alcohol syndrome (FAS; the consequences of prenatal ethanol exposure). Our experiments and those from other laboratories show that zebrafish is a useful model for mechanistic experiments, which should lead to a better understanding of this devastating birth defect syndrome.
