Research Summary
Our research is concentrated in two major areas. First, we aim to understand how the proteins involved in DNA repair, mutagenesis and other cellular responses to DNA damage are regulated. Some of our discoveries have the potential to improve chemotherapy. Second, we probe how nitrogen-fixing nodules develop on legumes, and the relationship between rhizobial functions required for nodule invasion/infection and mammalian pathogenesis.
