For nearly 30 years, Dr. Hayflick has studied a group of rare neurodegenerative disorders associated with brain iron accumulation. Her team, in collaboration with leading scientists from around the world, discovered the genetic underpinnings for PKAN, PLAN/INAD, BPAN, FAHN, MePAN, and several related disorders. They developed the first clinical tests, advanced understanding of basic disease biology, contributed key research resources, including animal models, and continue to drive rational therapeutics development in the NBIA disorders. Her research team spans from the bench to the bedside and beyond to the patient and family community. As a physician-scientist, Hayflick is deeply committed to the patients and families in the global NBIA community, working to improve their lives and relieve their suffering as a guiding force in her work.
