My general research interests concern the molecular analysis of early developmental events in amphibian embryogenesis. More specifically, I am interested in how cellular interactions and cell signaling affect cell fate and cell behavior in embryos. Current research involves examination of the function of a family of receptor tyrosine kinases in embryos of the frog Xenopus laevis.
