Research Experience

February 2006. Full-time position as an Assistant Research Scientist in Gloria Coruzzi's Laboratory at the New York University in New York, USA.
May 2002 - November 2005. Ph.D. student in the Biological Interactions Research Program at the University of Quilmes in Buenos Aires, Argentina. I did all research and laboratory work for my dissertation at the Institut de Recherche pour le Développement in Montpellier, France.
I studied the function of a metalloprotein using transgenic A. thaliana and actinorrhizal plants that carry genetic constructs with the reporter gene gus, and with over-expression and silencing of the protein using 35S promoter. Transgenic plants were tested in vitro and in vivo for biotic and abiotic stress.
March 1999 - May 2001. Research activities at the Biological Interactions Research Program at the University of Quilmes.
I studied plant development using nitrogen fixing bacteria, in addition to arbuscular mycorrhizas. Spot inoculation was also tested. Plants from different treatments were analyses by their nodulation, nitrogen fixation (measurement of acetylene reduction activity), mycorrhization and total phosphorus measure (Kendall test).
March 1997 - December 1998. Ad-honorem research activities at the Soil Microbiology Laboratory, School of Exact and Natural Sciences, University of Buenos Aires. Supervisors: Dr. Alejandro Pardo and Dra. Alicia Godeas.
I studied the interaction between Trichoderma pseudokoningii and arbuscular mycorrhizas in a green house, using soybean (dry matter and root colonization), and testing in vitro spore germination with soluble exudates and volatile substance of T. pseudokoningii.

Awards and Honors

2002-2005: Doctoral grant EGIDE/IRD (Institut de Recherche pour le Développement), Montpellier, France.
