Personal profile


Dr Tom B Letessier is a research assistant professor at the centre for marine futures, Oceans Institute, University of Western Australia since 2011. He has previously studied at the University of Aberdeen, and the University of St-Andrews.

Roles and responsibilities

I am responsible for implementing the National Environmental Research Program’s (NERP) project on the interactions of marine megafauna with ocean features such as canyons.

This involves, but is not limited to:

-Synthesising approaches used to understand marine megafauna (cetaceans, large sharks and fishes) interactions with oceanic features such as canyons, banks and marine cliffs.

-Compiling relevant databases for megafauna, biological oceanography and seabed topography as relevant to the project, and identify key focal study areas.

-Leading and participating in field programs, with responsibility for organisation, logistics, health and safety, and implementation.

-Maintaining communication with NERP team members in Node 3 and in other nodes as appropriate.

-Developing networks of colleagues working in related or complementary areas, nationally and internationally.

-Completing major statistical analyses of existing and new data sets.

-Presenting research results and conclusions in workshops and conferences.

-Publishing scholarly papers and reports related to this research

-Completing reports and prepare documentation associated with work accomplished.

Previous positions

My main interests lies in the environmental drivers of open-ocean and pelagic ecosystems. My PhD studies involved investigating the impact of bathymetry features on pelagic ecology using field sampling, statistical modeling techniques, and biochemical laboratory analysis such as stable isotopes and fatty acid. I have a keen interest in trophology, biodiversity and taxonomy. I am presently investigating the effect of bathymetry anomalies on apex predators, from the point of view of conservation and sustainable fishery management. Current research projects involve Shark Bay WA, The Timor Sea, Chagos/British Indian Ocean Territory, New Caledonia, and the Skagerrak coast of Norway
