Impact example:


Jon’s work as part of the team assessing delayed cord clamping has in combination with other trials in meta-analysis led to the widespread adoption of this practice across the world for preterm infants. The additional transfusion of blood from the placenta has been shown to increase survival and reduce brain haemorrhages that often cause disability.
