Canada Research Chair in Respiratory Ecology and Aquatic Conservation

Research Interests: Aquatic ecology and conservation, evolutionary and ecological consequences of respiratory strategies in fishes, physiological ecology, ecomorphology, adaptive divergence, tropical inland waters, Africa. Recent work focuses on divergent selection across oxygen gradients in fishes, the interaction of hypoxia with other environmental stressors (e.g., introduced species), and the value of tropical wetlands in the maintenance of fish faunal structure and diversity.
