Family and early life
He was born in Dulwich, England, in 1978. His mother Prue was a journalist and his father Robert was a patent agent. His older sister Steph taught him how to program the family's BBC Micro. He used this knowledge of programming to produce a crater investigation model in the physics department at Westminster which was of an extremely high standard. This was part of a physics project in which he was awarded a 15 Merit — an outstanding and very rare full mark.
He attended Westminster School, where he was part of the team representing the school in the British Informatics Olympiad. He began his undergraduate studies at Clare College, Cambridge focusing on Physics while studying a Natural Science Tripos. He graduated with a Master's degree in 2000.
