Sarah Johnson, a former freelancer, has taken the role as the charity aims to make Type 1 Diabetes a key public policy issue. She leads a team of five and reports to CEO Karen Addington.
As well as lobbying, the team will support families, friends and teachers of sufferers.
JDRF is a medical research charity that exists to find a cure for Type 1 Diabetes, a condition that is on the increase and usually manifests in children.
Johnson replaces freelance consultant Mark Flannagan, who was brought in to conduct a communications review earlier this year.
Flanagan, who has been in the role for the last three months on an interim basis, is a former deputy director of communications at ASH.
JDRF is also currently looking for a head of communications.
