I received a PhD in the Neurosciences Program (1992) in the University of Cadiz. My doctoral thesis was focussed on the study of the mechanisms of action involved in the analgesic effects of antidepressants. In 1992, I started a postdoctoral stage at the René Descartes University with a fellowship of the EU “Human Capital and Mobility”. My postdoc stage lasted 6 years (1992-1998). I also defended a second doctoral Thesis at the René Descartes University, 1996 (Russell Award). I had the opportunity to work in various projects including the phenotyping of mice with mutations in the opioid, cannabinoid and dopaminergic system that allowed us to characterize functions of the opioid system. In 1998, I joined Pompeu Fabra University (UPF). Since 2007 I lead the Behavioural Neurobiology Research Group (GReNeC-NeuroBio) (https://www.upf.edu/web/grenec) and since 2008 I am a Full Professor at the UPF.
