Current Research Interests

• Gas transfer, blood gas transport and acid-base balance in fishes. The central theme of this research centers on the role of stress hormones in controlling respiratory gas transfer and blood gas transport in fish during environmental disturbances.
• Relationships between ionic and acid-base regulation in fishes. This research concerns the physiological and molecular nature of gill transepithelial ion movements and their modulation during environmental disturbances.

Domaines de recherche

• Échanges gazeux, transport sanguin des gaz et régulation acido-basique chez les poissons. Le thême central de cette recherche est le rôle des catécolamines plasmatiques dans le contrôle respiratoire des échanges gazeux et transport sanguin des gaz lors de perturbations environnementales telles que l'hypoxie ou l'hypercapnie.
• Relations entre la régulation ionique et acido-basique chez les poissons. Cette recherche s'intéresse à la nature des mouvements ioniques transépithéliaux ainsi que leur variations lors de perturbations environnementales.
