Research Interests

During my PhD I studied the behavioural and physiological ecology of freshwater fish -   focussing primarily on the within- and among- individual variation in salmonid metabolism and how this can be influenced by its external environment and social interactions.

Since then my research interests have become more focussed on understanding the relationships between fish population status, water quality and stream habitat. This includes:

  • Effects of morphological and hydrological change on fish populations
  • 2D hydraulic modelling
  • Statistical hydraulic-habitat modelling
  • Transferability of locally derived habitat-abundance models and their potential for predicting the effects of changing flow regime
  • Hydrochemistry and stream ecology
  • Developing methods to provide information on salmonid habitat use in deep rivers

Collaborations

My primary collaborators include local fisheries trusts,  the UK Upland Waters Monitoring Network (http://uwmn.defra.gov.uk/sponsors/sponsors.php) and those centred at the University of Aberdeen.
