Professional background

After studying medicine at Oxford University and St Mary's Hospital Medical School, Joanna spent her paediatric training in St Mary's, Great Ormond Street, the Whittington, the Royal London and University College London Hospitals (UCLH). Her specialist training was in paediatric oncology, and she did several years of research looking at PET-CT scanning in paediatric cancers. Her work included collaborations to establish national and international guidelines for PET-CT in children.

After six months as a consultant at Great Ormond Street Hospital for Children (GOSH), Joanna returned to general paediatrics at UCLH, developing her interests in child safeguarding and adolescent medicine. She runs a general adolescent medicine service with a large multidisciplinary team, looking after young people with varied and complex illnesses. She is a trustee of the NSPCC and a Governor at The Children’s Hospital School - a school at both GOSH and UCLH that offers teaching and learning to patients throughout the care they receive. 

She has previously worked at the Lighthouse and is now also working at GOSH with the Perplexing Presentation Support Service. She is the clinical director of the new NHS Children and Young People’s Gender Service (London).
