I am a Professor of Economics in the Faculty of Business and Law and Director of the Centre for Blue Governance.

I specialise in development economics, particularly environmental or ecological economics. I explore the interfaces between the use of natural resources and the development of countries. My particular area of expertise is the 'Blue Economy' — the sustainable use of oceans and coastlines for economic growth while preserving the health of ecosystems.

I investigate how developing countries can benefit from the use of natural resources in a sustainable way, and, importantly, how to place a monetary value on the protection of the natural environment. My research helps countries to develop sustainably. It informs the implementation of policies that favour environmental protection while providing economic and social benefits.

I coordinate complex research projects with multidisciplinary teams in Europe, Africa, Asia, the Caribbean and the Pacific region, working in collaboration with national research institutions, universities and policy makers.

I've coordinated 40 international research and development programmes in the following areas:

  • Marine and coastal biodiversity and ecosystem services
  • Marine protected areas, including ecosystem valuation and payment for environmental services
  • Climate change
  • Ocean and coastal zone policy and governance
  • International and regional fish trade
  • Poverty and food security

I support many organisations to develop their strategies for the use of oceans and the coast. I coordinated Blue Economy Strategies for the African Union, the Intergovernmental Authority for Development (IGAD), the Government of Bangladesh and the Government of Seychelles. I also coordinated the Regional Action Plan for the Blue Economy of the Indian Ocean Commission.

I've authored or co-authored over 350 journal articles, book chapters, research reports, consultancy reports, media reports, conference papers and proceedings. I'm a reviewer for many scientific journals. 

I'm a scientific evaluator for several research councils in the UK, Europe, North America, Africa and Asia.


I have over 25 years of teaching and research experience. I became a Professor of Economics in 2018 and Director of the Centre for Blue Governance in 2019.

I'm currently an Invited Lecturer on the Master's program on Coastal Zone Management at the University of Antilles, Martinique and an Invited Researcher at the Caribbean Public Policy Research Centre. I'm also an Invited Professor at the Emerging Market Institute of Beijing Normal University, China.

I joined the University of Portsmouth as a Research Fellow in 1997. Before this, I was a teaching fellow for the Master’s programme in Marine Resource Management at the University of Québec in Rimouski, Canada.

I completed a PhD in Economics at the University of Portsmouth in 2012. I hold an MSc in Economics of Marine Resources, a Master's in Modern Philosophy and Contemporary Ethics and a Master's in Economic Science.

I welcome enquiries and applications from students wishing to be supervised in PhD projects broadly within the areas listed above.

Teaching responsibilities


I currently lecture on the following modules:

The Development Economics module has grown in popularity, attracting three times more students than it did five years ago. Student involvement is central to my lectures. 

Media availability
