Personal profile

Area of academic expertise - outline

My research is multidisciplinary and integrative, and I combine laboratory experiments and field surveys to address applied and basic research questions in aquatic ecology. In particular I am interested in:

  • Understanding and predicting impacts of invasive species
  • Predator-prey dynamics under changing environments
  • Multiple environmental stressors and how they affect biotic interactions

Current research activities

  • The attractiveness of shrimp feed in aquaculture
  • The reestablishment of fish communities on restored coral reefs
  • Impact of invasive prey on a native predator
  • Size determination of predator-prey interactions
  • Anthropogenic noise and its impact on biotic interactions

Desired research direction

  • Impacts of pollutants on predator-prey interactions
  • The role of the developmental environment in shaping future behaviour
  • Mathematical modelling of food webs

Target collaborative companies

  • Mars WALTHAM
  • Skretting

Target collaborative organisations

  • University of Exeter
  • University of Portsmouth
  • University of Witwatersrand, South Africa

Other areas of expertise available for knowledge exchange

  • Functional responses and associated statistical modelling
  • Marine invertebrate behaviour 
  • Animal husbandry and lab maintenance of specimens
