Dr Tom Jacques
Consultant Neuropathologist

Tom JacquesDr Tom Jacques runs a research group at the UCL Institute of Child Health focussing on brain tumours and paediatric epilepsy and provides the diagnostic neuropathology service for GOSH. He has held a Clinician Scientist Award for the past 6 years and have recently been awarded a nationally competitive HEFCE Clinical Senior Lectureship. Tom's research focuses on the role of stem cells in the development of paediatric brain disease. Specifically, he have recently shown that the major types of brain tumour can arise from stem cells and that the type of tumour is determined by the initiating genetic mutation (Jacqueset al.EMBO J 2010;29:222-35). Tom has also isolated a pathological stem cell from a malformation of cortical development in children with severe epilepsy (Yasinet al.Acta Neuropathologica 2010;120:85-96).
