Research Interests

Biological research has been transformed by the new science of genomics. Genomics is a powerful set of tools for examining all the genes or proteins in a cell simultaneously. Using genomics, scientists dissect the interrelationships among genetic networks and explore the molecular bases of biological processes.

My colleagues and I use genomics to understand the genetic organization of legumes, the plant family that includes crops like soybean, pea, and alfalfa. A key starting point toward our goal is sequencing the complete genome of a simple model legume known as Medicago truncatula. With this information, we are working to understand the molecular evolution that has taken place over millions of years and resulted in the modern crops.

Of special interest to us are the genes responsible plant interactions with microbes. There are two classes of genes we target: those that promote symbiosis with beneficial microbes and others that help to defend against disease pathogens. Many of these genes are members of large gene families that produce fascinating and important protein products. Understanding the molecular evolution and genomic organization of plant-microbe interactions is key to utilizing genetic knowledge to promote sustainable agricultural systems.
