Current Research

Our laboratory conducts research at the interface of chemistry and biology. We are particularly interested in employing chemical tools and principles to investigate cell migration and cellular signaling pathways. We are actively developing strategies for: 1) labeling proteins with fluorescent molecules, 2) controlling biological processes with precise spatial and temporal resolution, 3) engineering fluorescent proteins, and 4) quantifying signaling flux through biologically important pathways. These efforts are supported by a combination of multidisciplinary approaches including protein evolution, synthesis, and molecular biology.
