My general research interests lie in addressing how fish, especially elasmobranchs, deal with stressors in their day-to-day lives from a physiological perspective. My current work aims to integrate the fields of fish physiology, ecology and behavioural science to incorporate an understanding of the physiological mechanisms underpinning the role of the stress axis in governing predator-prey interactions in a number of teleost and elasmobranch species. My work will also aim to address some questions concerning basic stress physiological operations in these animals and will hopefully be employed to predict changes in predator-prey interactions in the face of increasing anthropogenic induced stress in fish. I’m also highly interested in any work concerning elasmobranch physiological and ecological dynamics.
