Awards & Achievements

Alexander von Humboldt Foundation Research Prize (2006)

Research Interests

Quantitative interactions and exchanges between organisms and their environments, with a broadly based comparative and evolutionary approach.

Respiration, metabolism and energetics of vertebrate embryos.

Cardiovascular and respiratory physiology of animals, particularly vertebrates.   Emphasis has been placed on the roles of diffusion and convection of respiratory gases in animals in extreme environments, for example, diving and burrowing species.

Comparative thermoregulation of diverse organisms, including plants and insects.

Physiology and biology of archosaurs.
