Biography

I am a Reader in Fish Biology (appointed 2/02) in the School of Ocean Sciences, Bangor University. I have now come full circle in my academic career as I graduated with a degree in Marine Biology and Zoology from UCNW Bangor in 1987. In 1989, I headed north to undertake doctoral research under the supervision of Prof. Dominic Houlihan at Aberdeen University. My Ph.D. examined how individual differences in feeding behaviour and protein turnover affected growth rates in rainbow trout and sea bass. Having completed my PhD in 1992, I remained in Aberdeen for 4 years postdoctoral research studying the physiological ecology of salmonids and flounder. In 1996, I was awarded a NERC Fellowship and I moved to the University Field Station (Glasgow University) on Loch Lomondside to examine the effect of intraspecific variation in physiological performance on growth and life history strategies in salmonid fish. In 1999, I 'popped over the pond' to Mustang Island on the Gulf coast of south Texas to work for Prof. Lee Fuiman at the University of Texas at Austin Marine Science Institute in Port Aransas. My research in south Texas examined the sublethal effects of pollutants on the behavioural and physiological performance of marine fish larvae. I returned to Menai Bridge in February 2002 where I lead a research group working on the behavioural and physiological ecology of aquatic animals.

Research Interests

My research interests fall broadly within the fields of physiological and behavioural ecology primarily using fish species as models although I also work on molluscs (e.g. scallops, mussels, cuttlefish) and crustaceans (e.g. crabs). My research interests focus on 5 main areas

  1. growth and energetics of aquatic animals (in particular protein synthesis/turnover and trade offs in energy allocation)
  2. repeatability of physiological performance
  3. individual variability in performance and its links to life history strategies and fitness
  4. the effects of contaminants on physiology/behaviour
  5. use of chemical tags (isotopes and trace elements) to examine feeding ecology and movement patterns.
