Entered the Faculty of Veterinary Medicine at the University Austral of Chile in 1984 and achieved the degree of DVM in 1989. In 1992 he attended the Master programme of Immunology at the Faculty of Medicine, University of Chile. In 1992 he received a doctoral fellowship from the German Academic Exchange Service (DAAD) to conduct a PhD thesis in Parasitology in Germany. He achieved his doctoral degree in 1998 at the Faculty of Veterinary Medicine, Justus Liebig University Giessen, Germany. In 2005 he achieved the status of Diplomate of the European Veterinary Parasitology College (DipEVPC). In 2005 he received a postdoctoral fellowship financed by the German Research Foundation (DFG) to conduct his habilitation thesis in Parasitology. Since January 2008 he holds the position of Senior Lecturer for Veterinary Parasitology at the Royal Veterinary College, United Kingdom and is a Visiting Professor of the University Austral of Chile. In 2009 he achieved his habilitation degree (Dr. habil.) in Parasitology at the Faculty of Veterinary Medicine, Justus Liebig University Giessen, Germany.In the last 14 years he has mainly been involved in the field of coccidian parasites (Eimeria bovis, E. ninakohlyakimovae, Neospora caninum, Toxoplasma gondii, Sarcocystis miescheriana). Within this field he has investigated the interaction of Eimeria bovis with its endothelial host cell and also the bovine immune response against this enteropathogen. Within the topic of parasite-host cell interactions he investigated the parasite-induced modulation of apoptosis, cytoskeleton, transcription, translation and metabolism by microarray- and proteome-based profiling of E. bovis-infected cells.
