Short info
I am marine ecologist with a keen interested in evolution and the ecology and biography of environmental change, with a fascination for polar ecosystems and the ocean twilight zone.

Research
My research focuses on understanding the mechanisms at the individual level that underlie macroecological and macroevolutionary patterns. Key aspects of my work include life-history theory, physiology, and the role of light regimes in governing foraging interactions and species distributions. I enjoy thinking broadly, linking data with theory and models, and exploring diverse biological disciplines.
