Research interests

My research is inspired by an interest in how marine animals make use of the three dimensional space and how they behave in relation to their physiological capacity and the surrounding environmental conditions. In particular, I am intrigued by the physiological adaptations of air-breathing marine animals and how they organize their underwater activities around the necessity to return to the surface to breathe. For this scope I have been using a wide range of telemetry devices including satellite relay data loggers and archival tags with an array of environmental and movement sensors. Most of my studies are carried out on both captive and free-ranging sea turtles, which are unique in the combination of a complex life history, ectothermy, and migratory behaviour. Unfortunately, they face numerous threats during their long lives and often die from interactions with human activities. Hence, I strive to focus my research on those cryptic aspects of sea turtle biology that can serve the cause of knowledge-based conservation.
In addition, I am generally interested in applying knowledge gained from scientific studies on physiological mechanisms and behavioural patterns of marine animals to improve their management and conservation and to promote animal welfare in research and maintenance.
