Nicholas Kevin Dulvy is a Distinguished Professor and Canada Research Chair in Marine Biodiversity and Conservation at Simon Fraser University.

He spent several years working for the UK Government Fisheries Agency before taking a position at Simon Fraser University in 2008.

[3] His contributions to marine ecology include providing evidence for fisheries-induced trophic cascades at the island scale on coral reefs[4] and the discovery that fishes are moving to deeper habitats in response to climate change.

[6] Dulvy's work is notable for its influence on biodiversity conservation, food security, and poverty alleviation.

In 2014 Dulvy was the primary author of the first global analysis of the vulnerability of chondrichthyans: "Extinction risk and conservation of the world's sharks and rays",[8] a collaborative effort involving 302 experts from 64 countries.
