Dr. Claudia Gray

Claudia Gray, EDGE of Existence Conservation Biologist

As the EDGE Conservation Science Manager, Claudia oversees the research supervision for EDGE Fellows and Hero Awardees, as well as the scientific research underpinning how EDGE identifies conservation priorities. Claudia previously worked as a Postdoctoral Research Fellow in Ecology and Conservation at the University of Sussex, where her research included an analysis of the global effectiveness of protected areas. She did her PhD and MSc at Oxford University, focussing on conservation strategies within oil palm landscapes of Sabah, Borneo.

Dr. Fran Cabada

Fran Cabada, EDGE of Existence Marine Biologist

Fran is the EDGE Marine Biologist. She supervises EDGE fellows and supports the development of our marine projects. Fran previously worked as a Lecturer in conservation and management of coastal-marine resources at Universidad Simon Bolivar in Venezuela, from where she also holds her Master’s Degree in Experimental Ecology and Ecological Data Analysis and her PhD on conservation and management of marine resources in the southern Caribbean. Fran is also a former EDGE coral Fellow; she completed her Fellowship on the pillar coral Dendrogyra cylindrus between 2014 and 2016.


Caroline Park

Rikki Gumbs, EDGE of Existence PhD Student

Rikki is the EDGE Postdoctoral Research Scientist, and works to incorporate the latest scientific advances into our prioritisation protocol. This includes updating our existing EDGE lists, creating new EDGE lists, expanding the scope of EDGE Zones, and working on the development of a new approach to identifying priority EDGE species. Rikki’s research also explores the relationship between phylogenetic diversity, trait diversity, and extinction risk. He oversees our many Masters student projects and co-supervises EDGE PhD students from partner universities. Rikki is passionate about the conservation of reptiles, and also supports our EDGE Fellowship and scale-up  projects.

He is based in North East India and has many years’ experience working in research and conservation of Asian elephants. For his doctoral research, he studied habitat suitability modeling of Asian elephants in a tropical forest of Assam, India. His research interests span population monitoring in tropical forests, human wildlife conflict and conservation protocols in trans-boundary landscapes. His recent work includes developing mitigation measures along highways to facilitate safe animal movement.


Dr. Caleb Ofori

Dr. Caleb Ofori, EDGE Regional Projects Manager for Africa

Caleb is the EDGE Regional Projects Manager for Africa. He provides training and supervision for current EDGE fellows and offers assistance to EDGE alumni in this region. Caleb is a passionate amphibian biologist and conservationist based in Ghana, with considerable experience in teaching, fundraising and managing conservation projects. His research has resulted in the discovery and description of new amphibian species to science. He founded Ghana’s first amphibian and reptile conservation NGO and spearheaded the establishment of municipal level protected area for an EDGE species (Togo slippery frog), which was also the focus of his EDGE Fellowship (2013 – 2015). Caleb holds a PhD in Wildlife Management from the Kwame Nkrumah University of Science and Technology, Kumasi, Ghana.


Dr. Paul Barnes

Paul Barnes, Social Dimensions Specialist

Paul is the EDGE Social Dimensions Specialist. He supports the Fellows to understand the social and political context of their projects and guides their social data collection, analysis, strategies for stakeholder engagement, and public awareness-raising. He is also responsible for the broader monitoring and evaluation of the EDGE programme. Paul a PhD in Environmental Anthropology during which he was a member of the Human Ecology Research Group in UCL Anthropology. For his PhD, Paul explored cross-culturally informed interdisciplinary research about indigenous and local knowledge, its position in conservation, and the political ecology of conservation in the Cyclops Mountains, home to EDGE mammals Attenborough’s long-beaked echidna and the black-spotted cuscus.
