Research Scientist

Benthic Ecologist focused on Vulnerable Marine Ecosystems. Expertise in applied use of advanced subsea technologies for mapping and monitoring deep-water ecosystems.

Current research and/or projects

I am a Research Scientist with the Quantitative Assessment Methods Section. My current project is focused on identifying Vulnerable Marine Ecosystems in the North Pacific Ocean using a combination of predictive habitat modelling and deep-water visual surveys.

Research and/or project statements

  • Benthic ecology of deep-water fish and invertebrate assemblages.
  • Species distribution modelling of cold water sponges & corals on northeast Pacific seamounts.
  • Influence of variable hypoxia on epibenthic fish and invertebrate communities in the northeast Pacific Ocean.
  • Community mapping, distribution modelling, and ecology of glass sponge reef communities
