Respiration, vulnerability, and fish size in a warming ocean
I study why some fishes are more vulnerable than others to fishing and climate change — linking gill surface area, oxygen supply, vulnerability indices, and long-term trends in body size.
About
I am a marine biologist with field experience from polar regions to temperate coasts. My doctoral work in Prof. Jessica Meeuwig’s Marine Futures Lab at the University of Western Australia links respiratory physiology to ecological vulnerability — testing how gill surface area and related traits relate to climate and fishing vulnerability, historical size declines, and temperature–length patterns in BRUVS surveys, using the Gill Oxygen Limitation Theory as an organising framework.
I also work as an expedition field scientist, combining ecological monitoring (including BRUVS and eDNA) with science communication for public audiences.
Research themes
- Gill surface area as a correlate of climate and fishing vulnerability
- Comparative cardio-respiratory traits in teleosts and elasmobranchs
- Historical recreational catch records and generational size trends
- Global BRUVS surveys: length–temperature patterns and survey design
