Zara grew up in the UK and achieved her BSc (Hons) Biological Sciences at the University of Liverpool.  She learnt to dive in Dahab, Egypt, which confirmed her interest in marine biology. Whilst diving in Thailand, Zara had her first encounter with a crown-of-thorns starfish (CoTS) outbreak and was immediately interested in the causes of these outbreaks and their effects on coral reef communities. Supervised by Prof Morgan Pratchett and Dr Vanessa Messmer within the ARC Centre of Excellence for Coral Reef Studies, Dr Symon Dworjanyn at the National Marine Science Centre, and Dr Scott Ling at the University of Tasmania, her PhD focuses on predation upon CoTS. Specifically, her research explores presumed anti-predator defences of the early life stages of this starfish, in addition to identifying new predators and determining patterns of predation upon larval starfish.
