My primary research interest is understanding the mechanisms allowing efficient symbiotic associations between plants and microbes, and applying this knowledge to maximize the benefits of such associations in agriculture. My specific goals are to (1) understand the genetic and molecular mechanisms allowing the establishment of mycorrhizal and nitrogen-fixing associations, (2) study the evolution of these mechanisms in order to identify critical innovations that allowed the development of these associations, and (3) use this knowledge to engineer more efficient associations (between non-leguminous crops and nitrogen-fixing bacteria in particular) in order to improve the sustainability of our agriculture for food, feed and biofuel production.

Research Areas:

  • Nitrogen Fixation
  • Legumes
  • Evolution

Current N-related Projects:

  • Evolution of nodule-forming symbioses and improvement of nitrogen fixation in non-leguminous crops
