Research
My main research focus is the structure, function and evolution of the vertebrate auditory system, which I investigate using techniques such as micro-CT scanning. I then use models of middle ear function to investigate the likely hearing range of the animal in question, in order to answer questions about how hearing is matched to particular acoustical properties of the environment that the animal lives in, and how the ear might have evolved.
I have long been interested in how small mammals can be adapted towards detecting low-frequency sound. For example, certain elephant shrews have enormously enlarged middle ear cavities, which allow these ears to transmit low-frequency airborne sound, while golden moles have massive ear ossicles, which may allow these burrowing African mammals to detect ground vibrations by means of bone conduction.
Recently I've become interested in certain other areas of comparative physiology, including fluorescence in frogs and nasal turbinate structure in seals.

Teaching and Supervisions
I am a Senior Fellow of the Higher Education Academy and a Fellow of the Academy of Medical Educators. I try to make sure that our students receive the best physiology teaching available. As part of this, I have introduced innovations including 'flipped classroom' to our courses, and I am the academic lead on a popular YouTube physiology channel (www.hippomedics.com).
I teach in the Natural Sciences Tripos (1A Physiology of Organisms, 1B Physiology, part II PDN research projects) and the Medical & Veterinary Sciences Triposes (1A Homeostasis). I am usually Senior Examiner and/or Course Organiser for one or more of these courses. I also run final-year projects in part II PDN relating to my research.
I am the Robert Comline Fellow in Physiology at St Catharine's College, where I supervise and direct studies in physiological subjects.
Other Professional Activities
Full member of the Anatomical Society, Member of the Physiological Society, and Fellow of the Royal Society of Biology.
Senior Fellow of the Higher Education Academy and Fellow of the Academy of Medical Educators.
