I had got my European PhD (10/03/2005) degree at the University of Murcia, being awarded with the National Excellence award. I have always got competitive research grant and contract at the University of Murcia, at the Animal hearth research center (CISA-INIA) and at IEO, having a permanent position at the last one. My field of expertise covers fish reproduction and immunology and the relation between both systems in health and disease conditions. I have performed studies on the ontogenetic development of fish, on the proliferative capability of fish testis and their regulation by sex steroid hormones and on the immune response against bacteria and virus. I have also worked developing molecular tools and vaccine strategies for fish, focussing on pathogens that persist inside the gonad.
