   RESEARCH INTEREST

    Since the discovery of penicillin in 1928 microbes have appeared that can resist the effects of this powerful class
    of antibiotics. By the end of the 1940's a large majority of bacteria had acquired resistance to penicillin as well
    as chemical cousins methicillin and oxacillin. Antibiotic resistant bacteria have a substantial impact on the treatment
    of infections. Even today, many bacteria are resistant to one or more of the 100 antibiotics in use and some
    strains are resistant to the "antibiotics of last resort" ; vancomycin and fluoroquinolones. The "coming plague" of
    multi-antibiotic resistant bacteria is fought by chemists and biologists in the laboratory everyday. Research efforts
    in our laboratory focus on the synthesis of small molecule inhibitors of bacterial resistance mechanisms. Towards
    this goal we utilize contemporary transition metal catalyzed reactions for synthesizing derivatives of lead
    compounds. Our chemistry efforts are strongly integrated and guided by the biological evaluation of our
    synthetic derivatives in hopes that this will lead to a new class of antibiotics effective for the treatment of
    infections caused by multi-anibiotic resistant (MAR) microorganisms.
