For over twenty years my research has focused on the effects of environmental factors (pollutants, temperature and daylength)  on the physiology and swimming performance of fish.  Throughout this period I have been fortunate enough to work with a number of  highly-talented postgraduate research students and academics. More recently, I have become involved in a study of visual capacities in Great Cormorants (Phalacrocorax carbo).

My other duties include providing IT support within the School of Biosciences and laboratory technical support  to Dr Saverio Brogna's research group.
