I first became interested in rocket landing while working at the NASA Jet Propulsion Laboratory in California. My colleagues and I developed new techniques for precision landing on Mars. The idea was to give a Mars lander the sensors and algorithms it required to work out where it is and how to get to where it needs to be. This required new developments in the field of Guidance, Navigation and Control (GNC), which I specialised in at Cambridge and later in my PhD at MIT.

In around 2010, I heard that SpaceX was interested in making their new rocket reusable. It was already highly optimised for going into space, but not for coming back to Earth. To achieve this, SpaceX needed someone who understood how rocket landing worked (and in particular, someone with knowledge of precision rocket landing).
