Research Overview:

My research interests have embraced a variety of marine ecological topics, ranging from the development and dynamics of hard substratum epifaunal ("fouling") communities, to responses of invertebrate larvae at metamorphosis and the population genetics of marine molluscs and crustaceans.  Latterly, my focus has been on wild salmon populations and their responses to environmental change.  A further long-standing interest has been the effects of ectoparasitic sea lice on wild salmonid popualtions.
