Research interests

We are investigating the cellular and molecular genetic mechanisms underlying vertebrate gastrulation, a crucial period of embryogenesis during which the germ layers are formed and then shaped into the vertebrate body plan with organ rudiments. Gastrulation entails a combination of inductive events that specify cell identities with massive cell movements and rearrangements that fashion the body plan. The complex and dynamic nature of gastrulation makes it a challenging but intellectually fascinating object of study. In humans, 25-50% of pregnancies end in early miscarriages of a largely unknown genetic origin. Moreover, the molecular regulation of tumor growth and metastasis show striking parallels to those underlying gastrulation movements, underscoring the practical significance of gastrulation research.

We are addressing the mechanisms of gastrulation in the zebrafish (Danio rerio), a system that affords a powerful combination of forward and reverse genetic analyses with embryological, cellular and molecular methods. We are also employing embryonic stem cells and tumor cell lines to test whether the new genes and mechanisms we implicate in zebrafish gastrulation are also involved in human development and disease. Our current experiments are focused on the roles of the Wnt, Wnt/Planar Cell Polarity, Stat3 and G-protein coupled receptor signaling pathways and epigenetic factors in the regulation of embryonic polarity and gastrulation movements.
