Julien was born in Brittany, France, where he completed a Bachelor in Biology in 2021. He then received his Master degree in Marine and Fisheries Management and Aquaculture in Corsica in 2023. Julien enjoys learning about and observing all living things, but his longest and strongest passion has always been the marine environment and its species. He has thus developed a keen interest in studying the best ways to protect them.

His first work experience in the marine field was studying the life traits of the critically endangered European eel in 2020 which he then followed, in 2023, with pelagic ecosystems assessment and long-term monitoring of two newly established Marine Protected Areas in Western Australia for his Master’s thesis. He has since been working in the Marine Futures Lab looking at the fish communities in charismatic regions of the world; from the Antarctica Peninsula to the remote islands of Pitcairn in the Pacific Ocean.

During this period he accepted a PhD offer to work in cooperation with the National Geographic Pristine Seas project at the University of Western Australia. The aim of this PhD is to study and develop baselines of remote pelagic ecosystem within the Pacific Ocean. These ecosystems are vital, but with the ever growing need for fish for human consumption, their remoteness is becoming less of a barrier against overfishing each passing day. The Pristine Seas project aims to protect these places and he hopes to help understand and showcase how vital and unique these places are.
