Michael Udvardi, Noble Foundation, USA
Michael Udvardi is Director of the Plant Biology Division at the Samuel Roberts Noble Foundation in Ardmore, Oklahoma, USA.
Dr. Udvardi earned his Ph.D. in plant biochemistry from the Australian National University in 1989.
He is primarily interested in how plants obtain nitrogen for growth, either as mineral nitrogen from the soil or from atmospheric di-nitrogen via symbiotic nitrogen fixation in bacteria. He has contributed to our understanding of symbiotic nitrogen fixation in legumes, especially of transport and metabolism in root nodules, using biochemical, molecular, genetic, and genomic methods. He was amongst the first to characterize ammonium and nitrate transporters in plants. Recently, his group has expanded its work on plant nitrogen to include associative nitrogen fixation, as well as nitrogen recycling during shoot senescence, in perennial plants. His group also has interests in plant acclimation and adaptation to abiotic stress, including drought and salinity. He was part of a large international team that sequenced and analyzed the Medicago truncatula genome and is now involved in efforts to sequence the related alfalfa (Medicago sativa) genome. He is also part of an international team that is trying to develop synthetic nitrogen-fixing symbioses in plants.
Dr. Udvardi has published over 150 papers in refereed scientific journals. He was Elected Fellow of the American Association for Advancement of Science in 2012 for his contributions to our understanding of legume biology, especially symbiotic nitrogen fixation.
