Quick CV

I have 8 years of experience in conservation policy, elasmobranch fisheries, and environmental assessment  in collaborative environments within NGOs, government, industry, and academia. I deeply value a diversity of people and perspectives in our pursuit of sustainable seas.

Marine Biologist


January 2019 - present

At Hemmera, I conduct marine environmental assessments and permitting for projects along the coast of BC. This includes biophysical assessments in the field (habitat characterisation, identification of vulnerable ecosystems and protected species, etc.), desktop studies, and stakeholder engagement.

Fishery Assessor

Ocean Wise

June 2018 - December 2018

I assessed the production and sustainability status of Canadian commercial fisheries based on the Standard for Fisheries, supplied by the Seafood Watch program (of the Monterey Bay Aquarium), which defines "sustainable seafood" as seafood from sources, whether fished or farmed, that can maintain or increase production without jeopardizing the structure and function of affected ecosystems.


Research Assistant
UBC Institute for the Oceans and Fisheries

August 2018 - October 2018

*Now published!* - I conducted a systematic review of the climate change literature to evaluate current knowledge of climate impacts on ocean ecosystem services. This work will contribute to a study led by the Changing Ocean Research Unit at UBC that aims to asses the impact of climate change on our progress toward meeting the UNDP's Sustainable Development Goals. This work was published as a paper entitled, "Climate impacts on the ocean are making the Sustainable Development Goals a moving target travelling away from us" in June, 2019 in the journal "People and Nature".
