My research interest is inspired by an interest in how animals respond physiologically and behaviourally to hypoxia and elevated pressures. I strive to integrate data collected from different levels of biological organization to better understand the organismal response to environmental challenges. I use a combination of theoretical, laboratory, and field studies to test hypotheses: what could be called “modern physiology”, where tools of other disciplines such as biochemistry, molecular biology, remote logging techniques and mathematics are applied to complement physiological data.
I believe that the comparative approach is particularly powerful when studying how physiological adaptations contribute to biological “fitness”, enabling animals to inhabit a wide range of habitats.
My current research uses both mathematical models and experiments to investigate when and how lungs collapse in marine mammals and if breath-hold diving animals ever experience N2 levels that could result in decompression sickness (DCS). If so, this raises the question: to what extent does N2 limit dive performance in diving animals?
