collaborators

Epilepsy care and research is a team sport and would not be possible without a huge range of clinicians and academics at Great Ormond Street Hospital UCL-GOS Institute of Child Health and beyond. We recognise the importance of this teamwork in maximising the impact of our research to ultimately care for children with epilepsy and therefore collaborate extensively with researchers and clinicians to help us realise our aims. Below you will find some photos of our team and links to the websites of some of our key collaborators.
