Details of specialism

I am interested in the parasites and diseases of aquatic animals with primary focus on farmed and wild Atlantic salmon (Salmo salar L.). I am also interested in providing advice for protecting fish health for sustainable aquaculture and conservation. 

Within the broad topic area my particular focuses currently include:

  • sea lice dispersal models and sea lice area-level populations
  • drivers of mortality of farmed fish, including climate change
  • interactions of pathogens of wild and cultured salmon
  • routes of spread of pathogens, including contract networks and imports

Main policy links:

  • fish and shellfish health advice
  • sea lice management practices and policies
  • epidemiology for disease management
  • marine planning advice
  • impacts of climate change on fish health
  • emerging and notifiable diseases

External committees and responsibilities

  • invited reviewer for scientific journals
  • invited reviewer for science funding proposals in UK, Norway and Canada
