Ann G. Clarke (née Jewkes) is a British immunologist and co-founder of the Frozen Ark project.
[1] Clarke's research focused on the immunological relationship between mouse mothers and embryos.
[1] She and her husband, Bryan Clarke, made several scientific expeditions to French Polynesia, where they realised that the partula snail was facing rapid extinction after the introduction of a predator as a biological control for a different species.
Inspired by this, they and Anne McLaren (1927–2007) founded the Frozen Ark project to preserve the DNA of species threatened with extinction.
[2] In 2017 Clarke was the subject of an episode of BBC Radio 4's The Life Scientific.
