Associate Professor Tim Langlois serves in the School of Biological Sciences and is affiliated with the UWA Oceans Institute at The University of Western Australia. He holds a BSc from Wales and a PhD from Auckland. His research interests include the ecology of marine crustaceans, ecology of marine fishes, marine diversity and conservation, experimental ecology, and multivariate analysis. Langlois is engaged in international collaborations to synthesize global perspectives on the impacts of long-term and acute environmental and anthropogenic disturbances in marine ecosystems. In Australia, his research examines continental-scale changes in ecological patterns as revealed by analyses of non-destructive video surveys of fish assemblages, providing students with insights into macroecological processes at local and global scales.

Langlois's career includes previous positions as Research Fellow at the UWA Oceans Institute and lecturer in the School of Plant Biology. He accepts PhD and other higher degree by research students. Key contributions feature the Benthic Observation Survey System (BOSS) for surveys of marine benthic habitats (Methods in Ecology and Evolution, 2025), CheckEM: An open-source toolkit for standardising, cleaning and visualising stereo-video fish survey data (Methods in Ecology and Evolution, 2026), A fine-scale fish population model reveals how integration of spatial and temporal management can maximise conservation and fisheries benefits (Journal of Applied Ecology, 2025), Plastic contamination in commercially valuable decapods caught near a major Australian urban centre (Environmental Pollution, 2026), and Deciphering the footprints of predator–prey interactions on coral reefs: seasonal dynamics and environmental drivers of reef halos (Coral Reefs, 2025). He received the Vice Chancellor's Award for Collaborative Indigenous Research Partnerships in 2023. His work contributes to Sustainable Development Goal 14: Life Below Water.
