Bio:

I was born in the Australian Northern Territory but grew up in Houston Texas before moving back to Australia to study marine biology. I graduated with a Bachelor of Science in 2024 and have since been working as a marine scientist specialising in pelagic and benthic ecology. I have used data gathered from baited remote underwater video systems (BRUVS) to explore the diversity, distribution, abundance, size and behaviour of fishes and sharks. This research directly relates to my master’s thesis which investigates the potential drivers behind why some fish choose to swim with certain host sharks over others. Additionally, I have fieldwork experience in deploying BRUVS in pelagic and benthic environments.
