Originally from England, I first learned to dive so that I could go cage diving with great whites off Guadalupe Island, Mexico, in 2008. From that first shark encounter onwards, I have been utterly hooked on the underwater world, and particularly on the issue of shark conservation. Whilst studying for my degree in London, I worked at London Aquarium, before going to Mozambique to research whale sharks off Tofo. I completed my PADI Instructor’s course while living in South Africa, and spent nine months teaching and guiding on Aliwal Shoal, where I set up a tiger shark ID project and began writing for the conservation organisation Shark Angels. After a seven month trip teaching around South East Asia, I'm heading back to Africa to explore the incredible dive sites of Tanzania.
