I am a fish physiologist and I’m interested in how fish sense, interact with and respond to their environment, linking environmental changes or challenges to whole animal physiology, behaviour and ecology. My early work has focused on the effects of low oxygen (hypoxia) on the cardio-respiratory responses of fish and its effects on development. This has sparked an interest in the neural control of breathing in fish.
My PhD focused on the roles of oxygen chemoreceptors in the response to hypoxia in both water and air breathing fish. During my postodoctoral work I have been studying the effects of climate change on fish physiology, particularly the effects of ocean acidification on olfaction (under the supervision of Dr. Rod Wilson) and sound detection (involves a close collaboration with Dr. Steve Simpson, an expert in the effects of anthropogenic noise on fish). In my current work I have discovered a new physiological mechanism for how ocean acidification affects the behaviour of fish.
