I am a molecular immunologist working on a variety of animal species to examine the amazing diversity and pathogen targeting ability of innate immune molecules. My lab uses high-throughput sequencing and other molecular techniques to answer comparative immunological and physiological questions in a variety of species including crustaceans and molluscs. In addition, we are examining the host-pathogen-environment interactions between a variety of marine pathogens, pollutants and their hosts.
