Profile
My research focuses on the design of fluorescent protein biosensors. Nature has provided a vast array of proteins which bind efficiently to molecules which my research group is interested in detecting. One of the goals of my group is to design a biosensor for glucose. The constructed optical biosensor may be used to measure glucose concentrations in complex media such as blood serum. A second main project in my lab, and in collaboration with Sabatino D'Auria (Institute for Protein Biochemistry, Naples, Italy), involves the characterization of an arginine binding protein from Thermotoga maritima. Finally, my lab collaborates with Dr. Malcolm Hill (UR Biology) on a chemical ecology project. Our goals are to isolate and characterize secondary metabolites from the symbiotic microbes associated with the Chesapeake Bay sponges, Clathria prolifera and Halichondria bowerbanki. We are interested in linking the biosynthetic genes and pathways with the corresponding microbial pigments in these organisms.
