My name is Javier Serradilla Rodríguez and I’m from Madrid, Spain. Graduated in Dietetics and Nutrition (Madrid, 2006-2008) and later in Medicine (University of Salamanca, 2008-2014), I completed my training as a specialist in Pediatric Surgery at La Paz University Hospital of Madrid in 2020. During my specialization, I spent several months in foreign centers learning from other important groups in the field of transplantation (Seattle Children's Hospital, Seattle, United States; Sahlgrenska University Hospital, Götenborg, Sweden) and I got some other degrees about transplantation and health research (master's degrees in Hepatobiliary Surgery and Liver Transplantation; master's degree in Methodology for Research in Health Sciences). Since 2020, I am an attending doctor of the pediatric transplantation team of the Hospital La Paz of Madrid, Spain. Also, I am currently doing my PhD about the viability of the intestinal grafts in the IdiPAZ (Hospital La Paz Institute for Health Research) where I am part of the transplant research group.
