Margaret has been dedicated to improving diabetes care through better diagnosis. She is the leading nurse for monogenic diabetes in the UK and provides advice to clinicians across the world regarding the management of this condition. She set up a national network of genetic diabetes nurses in 2002 to increase awareness of this condition (which is initially misdiagnosed in 80% of cases, resulting in patients being treated with unnecessary insulin injections). She was one of 70 national NIHR70@70 Senior Nurse Research Leaders (driving innovation and new roles to increase research awareness and engagement within clinical care) and has received the prestigious Florence Nightingale Foundation Leadership Scholarship.
