Pablo is a Research Fellow in Food Systems. His research focus on the investigation of livestock food value chains in the city of Nairobi, Kenya, and in the risk of zoonotic disease emergence within these chains. His work is also to investigate the economic impact of several animal diseases in the UK and in Europe.

Pablo was graduated in Veterinary Medicine in 2005 by the University of Cordoba, Spain. He undertook a MSc in veterinary epidemiology at the RVC and, subsequently, worked in the epidemiology division of the same institution for two years before starting his PhD in September 2009. For his PhD he investigated the epidemiological and economical impact of porcine post-weaning multi-systemic wasting syndrome in England. In addition, his research also focused on the investigation of pig farmers' decision making process for disease control. He graduated from his PhD in 2012 and started a post-doctoral research fellowship in food systems at the RVC.

Pablo's research investigates the risk of zoonotic disease emergence in the different livestock value chains of the city of Nairobi. He aims at identifying the different 'food routes' within the chains and their corresponding critical control points.His research also aims at modelling the livestock food system for the assessment of food safety and food security risks and of the efficacy of possible interventions.

His main interest lies in understanding the epidemiological and economical impact of diseases in the different livestock value chains and in the food system as a whole. He is also interested in the development of decision support tools for disease control, and for the different people in the chains, in order to help to improve food safety, food security and to optimize production process and animal welfare.
