Oscar is a Post Doctoral Research Fellow within the Centre for Marine Ecosystems Research in the School of Science.


I have over seven years research experience in marine ecology and palaeoecology, and in marine biogeochemical cycles. In Spain I worked at the Centre for Advanced Studies of Blanes and the University of Santiago de Compostela.

  • 2012: Post Doctoral Researcher, School of Natural Sciences.
  • 2011: Research Contract, University of Santiago de Compostela, Project “AGRIWESTMED - Origins and spread of agriculture in the south-western Mediterranean region”. Coordinator: Antonio Martinez cortizas.
  • 2005-2010: Research Contracts and Fellows, Centre for Advanced Studies of Blanes, Projects “SUMAR II - The carbon sink associated with marine macrophytes and development of their potential in paleoecology and environmental management”; “SUMAR - El papel de las praderas marinas mediterráneas en el ciclo global del carbono”; “CARBOMED - Magnitude of the carbon sink associated with the seagrass Posidonia oceanica and potential in paleoecology”; “Asistencia técnica para el estudio de confirmación de la evaluación de la calidad ambiental de las masas de agua costeras utilizando macroalgas e invertebrados bentónicos como bioindicadores”; “WADI - Sustainable management of the Mediterranean coastal fresh and transitional water bodies: a socio-economic and environmental analysis of changes and trends to enhance and sustain stakeholder’s benefits”.
