Personal profile


I am a Principal Scientist and advisor at the Centre for Environment, Fisheries and Aquaculture Science (Cefas). I lead on mixed fisheries and how technical interactions affect management outcomes for demersal stocks.

I have over 15 years’ experience in policy and fisheries management advice, including advising Government Ministers and senior officials. He is a former chair of ICES working groups on mixed fisheries advice and mixed fisheries methods (WGMIXFISH) and recently chaired a workshop on the next generation of mixed fisheries advice (WKMIXFISH).

I lead research projects with a focus on applied management solutions to address the challenges mixed fisheries present, addressing questions of sustainability, trade-offs, and alternate management approaches to traditional single stock management. As part of this he coordinates Cefas’ Food from Water subtheme on the application of mixed fishery and multispecies approaches.

Areas of Expertise

  • Mixed fisheries
  • Population dynamics
  • Modelling
  • Fleet dynamics

Key Research Interests

A focus of my work is on coupling population dynamics and fleet dynamics in bioeconomic simulation models to understand fishery interactions and the consequence of management decisions for different fleets and fish populations. He also works on spatiotemporal modelling of fisheries independent and dependent data to understand spatial interactions between fish populations and fleet activity, and methods to evaluate the impact of technical measures (gear changes, spatial closures) on management outcomes.

Expertise related to UN Sustainable Development Goals

In 2015, UN member states agreed to 17 global Sustainable Development Goals (SDGs) to end poverty, protect the planet and ensure prosperity for all. This person’s work contributes towards the following SDG(s):

  • SDG 14 - Life Below Water
