Since 1985, researcher at CENA/USP in the area of nuclear and related techniques in agricultural productivity studies. Consultant for the International Atomic Energy Agency and ad hoc consultant of FAPESP, CNPq, EMBRAPA and PADCT-MIC
Have experience in animal science with an emphasis in animal feed assessment, quantification and qualification of bioactive molecules and nutritional strategies for sustainable production of ruminants and food security:
• use of radiotracers in animal body composition studies (3H), bioavailability of phosphorus (32P) and calcium (45Ca) in supplements for ruminants, mineral metabolism in domestic animals in Brazil (32P) and Radioimmunoassay (125I);
• in vitro gas production test (syringes and transducer) to evaluate co-products, tanniniferous plants and plant secondary metabolites as modifiers of ruminal fermentation;
• use of tracers for quantifying the ruminal microbial mass (15N and purine derivatives) and diet food constituent (δ13C and δ 15N);
• in vivo quantification of enteric methane production (chambers and SF6 tracer) in studies of fibrous residues and pastureland in strategies to increase the sustainable production of ruminants.
