Fish physiology, behaviour,

and conservation

ABOUT ME

I am a comparative and evolutionary physiologist at Wilfrid Laurier University, Waterloo, ON, Canada. The aim of my research program is to understand how animals integrate physiological and behavioural responses to changing environments, how these responses evolve, and what happens when these responses feed back upon one another. A major focus is understanding the functional morphology of fish respiration and what this means for performance in different environments. I am also very interested in understanding how intra- and inter-specific differences in respiratory performance and other metabolic traits influences behaviours such as habitat choice. My work takes a highly comparative approach and is focused around two model systems: (1) the rivuline killifishes, a species-rich clade of tropical fishes that includes amphibious species that can survive for months out of water, and (2) North American cyprinids, especially the endangered redside dace. For more information about these projects, visit my Research page.

I currently hold an NSERC Postdoctoral Fellowship at Wilfrid Laurier University, where I'm working with Jonathan Wilson. Previously, I was an Eastburn Postdoctoral Fellow at McMaster University where I worked with Graham Scott and Sigal Balshine, a ReNewZoo Postdoctoral Fellow at the University of Windsor where I worked with Trevor Pitcher, and I completed my PhD at the University of Guelph with Patricia Wright.

RESEARCH INTERESTS

THE BEHAVIOUR-PHYSIOLOGY NEXUS

 

The phenotype of animals is shaped by the surrounding environment (phenotypic plasticity), but animals can also choose which environments they experience. I am interested in how these processes interact, and what this means for animals facing changing environments.

 

CONSERVATION BIOLOGY

Why are some fishes endangered, while others are ubiquitous and even invasive? I am interested in understanding the physiological basis of these inter-specific differences, and I work with government and non-profit conservation practitioners to use these data to help endangered species recovery.

FUNCTIONAL MORPHOLOGY
 

The structure and function of fish gills depends on many factors, including metabolic demand and environmental challenges. I am broadly interested in how these trade-offs shape fish gills both within lifetimes (phenotypic plasticity) and over evolutionary time, and what this means for performance.
