Research Description

The research efforts of my laboratory have focused on understanding the molecular mechanisms by which signals are transmitted from cell surface receptors to biological effectors. In particular, we have been interested in identifying new signaling molecules that influence the growth and differentiation of mammalian cells. Three areas of research are currently being pursued in the laboratory.
