I study the fidelity of genome replication by viral and bacterial model systems. Why are replication enzymes so accurate? Can the mutation rates of viruses be modulated using nucleic acid analogues? We try to answer these questions by characterizing the mechanisms of DNA and RNA replication using techniques from molecular biology, X-ray crystallography, and biochemistry. I am also interested in the interactions between viruses and their receptors at the cell surface.
