Research statement

Genomics of Plants, Symbiosis and Disease Resistance 
My colleagues and I are interested in the genes that enable plants and microbes to communicate at a molecular level. We are especially interested in legumes (soybeans, peas, alfalfa, etc) and their symbiotic relationship with rhizobial bacteria. This symbiosis leads to the formation of root nodules, novel organs where plants and bacteria work together to fix nitrogen into a form that is biologically useful, an important source of natural fertilizer worldwide.

We primarily use the tools of genomics (massive DNA sequencing combined with computational data-mining) in our work. The starting points are the genome sequences of two important legume models, soybean and Medicago truncatula. Building on these data resources, we work to understand the process of legume-bacterial evolution that has taken place over millions of years and resulted in the modern crops grown today.

Often, the same genes controlling symbiosis are also responsible for defense against disease pathogens. Understanding the genome architecture of symbiosis and disease resistance genes provides essential insights into sustainable strategies to manage and exploit plant-microbe interactions in agriculture.
