Areas of Research Expertise
  • Understanding and engineering beneficial associations between plants and microbes to improve agricultural productivity, protect the environment over the long term, and enhance human welfare
  • The signals and signaling pathways controlling plant - microbe symbioses
  • Mutualistic associations of plants with arbuscular mycorrhizal (AM) fungi that improve the plants ability to acquire nutrients, especially phosphate and nitrogen, from the soil and their resistance to biotic and abiotic stresses
  • Bacterial signals named Nod factors which are necessary for nodule development and infection of plant roots
  • Plant mutants affected in nodule development, infection thread formation, and early Nod factor responses in the model legume Medicago truncatula
  • DMI1's localization to the nuclear envelope
  • Molecular determinants which explain genetic differences observed between Medicago and Lotus
  • A 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGR1) interacting specifically with DMI2/NORK and required for root nodule formation
  • DMI1's control of the colonization of plants by human enteric bacterial pathogens such as Escherichia coli O157:H7 and Salmonella
  • Techniques to characterize the metabolome, proteome and phosphoproteome of M. truncatula
  • A high-throughput procedure based on real-time PCR to quantify soybean rhizobia in the soil in just a few days
  • Impact of drought on the survival of soybean rhizobia in the soil
  • Characterization of Nod and Myc factor signaling in seeds, the characterization of physiological and environmental factors affecting this growth stimulation, and the direct manipulation of symbiotic genes to stimulate plant growth
  • Characterizing rhizobia using their Nod factors to activate the mycorrhizal pathway in cereals (maize, rice…) and colonize them efficiently
  • Improving nitrogen fixation of rhizobia by hosting them in nodule-like structures
