Dr Soumya Mukherjee is a consultant neurosurgeon and author trained at Cambridge, Oxford and Harvard who has spent his career operating on the human brain.

Through thousands of hours in the operating theatre he has witnessed both the extraordinary resilience of the brain and the devastating consequences when it begins to fail.

Today he is on a mission to bring the science of brain health out of the operating room and into everyday life - showing how we can protect, strengthen and future-proof the most important organ we possess.
