He studied Biology in the University of Barcelona (UB) and received his doctorate from the University of Alcalá de Henares (1983) for his work on the transport of nutrients in the placenta under the direction of Professor Miguel Ángel Lasunción and Professor Emilio Herrera (Ramón y Cajal Hospital, Madrid). He was Tenured Professor of Physiology in the Faculty of Medicine in the University of Extremadura (1984-86), where he studied the role of Meister's cycle in the transport of amino acids in the placenta with Prof. José Viña

In the period from 1986-1987 he studied the zoning of the hepatic metabolism of fructose 2,6-biphosphate with Prof. Joseph Katz (Cedars Sinai Medical Center, Los Angeles, CA, USA). Tenured Professor (1987) of Biochemistry and Molecular Biology (BQBM) in the UB, combining his teaching with a collaboration with Prof. Heini Murer (University of Zurich) cloning the heavy rBAT chain, thereby discovering the Heteromeric Aminoacid Transporters (HAT) (1992).

BQBM Professor in the UB (1995). In Barcelona he identified two genes for cystinuria and the gene for lysinuria with protein intolerance (1999). He is Group Head in the IRB Barcelona (2002), where he is resolving the atomic structure of a prokaryote homologue of the light subunits of the HAT (2011).
