In 2015, she moved to the Institute of Metabolism and Systems Research (IMSR) at the University of Birmingham where she leads the Pituitary theme. She has established national and international collaborations and she is actively involved with patient support groups and with national/international bodies and societies. She is the Lead of the Academic Clinical Training in Endocrinology and Diabetes at the University of Birmingham and the IMSR Lead for Continuous Professional Development.
