The Team

The NETS team is made up of a range of people, including paediatric surgeons, statisticians, epidemiologists, parents and patients. NETS is based around collaboration between different centres both in the UK and abroad, so whilst a lot of the team are based in the National Perinatal Epidemiology Unit, some are based as far away as Glasgow and Vancouver.

Mr Benjamin Allin

Ben is a paediatric surgical registrar, and Doctoral Research Fellow. He graduated from Imperial College School of Medicine in 2010 and undertook his foundation training in London. In 2012 he moved to Oxford to take up a post as an Academic Clinical Fellow in paediatric surgery, joining the National Perinatal Epidemiology Unit at the same time. His work focuses on attempting to identify factors that affect outcomes for infants who have undergone early surgical intervention. This work has been based upon using the BAPS-CASS framework to carry out large-scale observational studies. Ben was recently appointed as a National Institute for Health Research Doctoral Research Fellow in order to improve outcomes in paediatric surgery through the development and implementation of core outcome sets.
