Main Research Interests

1) Ammonium use efficiency in eukaryotic organisms (yeast and plants): toxicity response and tolerance mechanisms; Isotopic fractionation process in yeast and plants; Natural isotopic signature (δ15N and δ13C); stable isotopes labeling studies (15N, 2H and 18O) in tissues;
2) Nitrogen (N) nutrition in plants: nitric, ammoniacal and ureic nutrition; C/N Metabolism responses in plants to N nutrition. Use of urease inhibitors in crops. Urea cycle significace in N metabolism of plants grown with different N sources (urea, ammonium, nitrate).
