Dr Sara Ghorashian

Consultant Paediatric Haematologist and Honorary Senior Lecturer


Sara Ghorashian qualified from Oxford University and undertook haematology training at the Hammersmith and Royal Free Hospitals. She obtained a PhD at University College London (UCL) in the use of gene-engineered T cells for cancer immunotherapy. More recently, her post-doctoral studies at the UCL Great Ormond Street Institute of Child Health involved translation of CD19CAR T cells as therapy for childhood acute lymphoblastic leukaemia (ALL) from bench to bedside. Her research interests are cellular immunotherapy for haematological malignancies and T cell immunobiology.

She has clinical interests in paediatric malignant haematology, and leads on cell therapy and research within the department. She is a co-investigator on two CAR T cell studies for ALL, and actively involved in implementing new studies in order to improve outcomes for children with high risk or relapsed haematological malignancies.
