Dr Rui Vieira

Senior Fisheries Scientist

Rui is a Senior Fisheries Scientist with over 10 years’ experience in deep sea science.

Rui P. Vieira joined Cefas in 2017 after completing a PhD in Ocean and Earth Sciences at the University of Southampton. He leads science on deep-water fisheries and work relating to conservation and sustainable use of marine fisheries resources. Rui’s main research interests include fisheries ecology, fish biology and drivers of functioning of deep-sea ecosystems.

Rui provides advisory support on assessments and technical measures relating to deep-water fish stocks and ecosystems. He is member of the ICES Working Group on the Biology and Assessment of Deep-sea Fisheries Resources (WGDEEP) and Deep-water Ecology (WGDEC), which he co-chairs since January 2022.

Rui holds an Honorary Lectureship in the School of Environmental Sciences at the University of East Anglia and is also a member of the Council of the Fisheries Society of the British Isles.
