Research

I study the symbiosis between legume plants and nitrogen-fixing soil bacteria (rhizobia). Rhizobia gain entry into legume roots and subsequently convert atmospheric nitrogen gas into ammonia (nitrogen fixation). Ammonia is then released to the plant, serving as an important source of nitrogen. In return, the plant provides the necessary nutrients to support rhizobial metabolism. In contrast to nitrogen fertilizer production using fossil fuels, nitrogen fixation is a natural process and a key component of sustainable agriculture. I am interested in identifying plant genetic factors which can be harnessed to enhance symbiotic productivity.
