    Collapse Overview
    Signal transduction networks enable cells to respond to the world around them. To uncover how these signaling networks generate proper responses, we need not only a parts list but also an understanding of how their constituent molecular components work together to process information. I have devoted my lab to developing technologies that will enable us to answer signaling questions that have not been possible to address before. My primary interest is to understand the signaling circuits that organize cell polarity. We take advantage of advanced microscopy techniques in conjunction with techniques to rewire cell signaling or to activate and inhibit signaling on a subcellular level. We aim to move beyond a parts list of components involved in migration to a systems level understanding of cell polarity.
