I am a PhD candidate at the University of Guelph under the supervision of Dr. Patricia Wright. Broadly, I am interested in understanding how, and why, amphibious fishes leave water. The transition from water to land poses considerable challenges for gas exchange, osmoregulation, nitrogen excretion, feeding, and locomotion. Nevertheless, >200 species of extant amphibious fish move between aquatic and terrestrial environments as part of their natural history. While many amphibious fishes have fixed adaptations to help overcome these challenges (e.g., lungs of lungfish), others use phenotypic flexibility (reversible acclimation) to facilitate the invasion of land.My research is focused on skeletal muscle remodeling in amphibious fishes, and how reversible changes to the musculature can improve the locomotor performance of amphibious fishes in both aquatic and terrestrial settings. I am particularly excited about the link between skeletal muscle phenotype and metabolism, and how the capacity for phenotypic flexibility changes across ontogeny.
