Sean Ainsworth was, for 20 years before retirement, a Consultant Neonatologist working in NHS Fife. His neonatal training in the North East of England brought him into contact with early editions of the Neonatal Formulary. He became involved with it when the 3rd edition was published in 2000, eventually taking over the writing and editing of the 7th (2014) and 8th (2020) editions. In addition to pharmacology, Dr Ainsworth has an interest in newborn resuscitation. He was a member of the Resuscitation Council (UK) Newborn Life Support sub-committee and of the European Resuscitation Council's Newborn Life Support Science and Education Committee.
