Over the last few years she has concentrated on Iberian pig metabolic characterization, investigating nutritional requirements (particularly amino acids and energy) during different growth phases. Her research interests include the effects of immunocastration on productivity and meat quality, links between amino acid and lipid metabolism, and consequences on meat quality. She has participated in nearly 30 research projects and contracts with international (including H2020 project TREASURE), national, and regional funding, in many of them as a research leader. She has authored over 70 SCI papers and many professional articles and congress contributions.
