Daphne du Maurier Building, University of Exeter,  Penryn Campus, Penryn, Cornwall, TR10 9FE, UK

I am a conservation biologist working at the Peruvian non-governmental organization ProDelphinus and as a Darwin Research Fellow at the University of Exeter. My research interests centre around understanding the interactions of Peruvian fisheries with threatened and endangered marine fauna, including sea turtles, seabirds, small cetaceans and sharks. This includes multi-disciplinary work to understand the spatial and temporal distributions of species and their population status; fisheries monitoring and management; and bycatch mitigation research and experimentation. This work requires the use of a wide range of techniques including onboard observer monitoring, satellite tracking, bycatch mitigation technology trials and Rapid Assessment surveying. My work always includes strong educational and awareness raising components and emphasizes working with local stakeholders to promote long term sustainability. I also maintain active studies of the marine otter. Additional interests include conservation and management of Hawaiian monk seals and hawksbill sea turtles.

I have extensive international research experience including in the United States, Peru, Costa Rica, Suriname, Chile, and Palau. My work to date has resulted in numerous published as well as other reports, book chapters and conference presentations.

Broad research specialisms:

Ecology and conservation of threatened and endangered marine fauna, including sea turtles, seabirds and marine mammals and interactions with fisheries, primarily small-scale fisheries. My work is very much applied research focused on understanding the overlaps between human and natural systems and identifying and implementing solutions that allow for the long-term sustainability of these animal populations and fisheries.

Qualifications

  • MEM Coastal Environmental Management, Duke University, 2003
  • MSc Environmental Science, SUNY College of Environmental Science and Forestry, 1997
  • BA Political Science & Sociology, Bucknell University, 1994

Research interests

I am a conservation biologist working at the Peruvian non-governmental organization ProDelphinus and as a Darwin Research Fellow at the University of Exeter. My research interests center around understanding the interactions of Peruvian fisheries with threatened and endangered marine fauna, including sea turtles, seabirds, small cetaceans and sharks. This includes multi-disciplinary work to understand the spatial and temporal distributions of species and their population status; fisheries monitoring and management; and bycatch mitigation research and experimentation.

My work always includes strong educational and awareness raising components and emphasizes working with local stakeholders to promote long term sustainability. I also maintain active studies of the marine otter. Additional interests include conservation and management of Hawaiian monk seals and hawksbill sea turtles.

Research projects

My primary works falls under the Darwin Sustainable Artisanal Fisheries Initiative (Peru) led by Dr. Brendan Godley, University of Exeter. This multi-year project, as well as companion and related studies with which I am involved through my work with ProDelphinus all revolve around different aspects of monitoring the distribution, abundance and bycatch of threatened and endangered marine species – including sea turtles, seabirds, marine mammals and sharks – and trialing and implementing measures to mitigation these fishery interactions. This research includes monitoring of small-scale longline and net fisheries, work with threatened and endangered species including the waved albatross and leatherback and hawksbill sea turtles, and trialing novel bycatch mitigation technologies like acoustic alarms (pingers) and net lighting.

Grants/Funding:

At any one time I work on multiple projects that receive funding from various sources. Current and previous project funders include: Agreement on the Conservation of Albatrosses and Petrels, American Bird Conservancy, Birdlife International-Albatross Taskforce, Cetacean Society International, Cleveland Metroparks Zoo, Columbus Zoo and Aquarium, Conservation Leadership Programme, Darwin Initiative, Duke University, Fulbright Commission, IdeaWild, International Association of Antarctica Tour Operators, International Fund for Animal Welfare, International Seafood Sustainability Foundation, National Fish and Wildlife Foundation, Oak Foundation, Overseas Research Students Award Scheme, Pacific Seabird Group, People’s Trust for Endangered Species, Permanent Commission for the South Pacific, Rufford Foundation, Societe D’Encouragement pour la Conservation des Animaux Sauvages, University of Exeter, US National Oceanic and Atmospheric Administration and Whale and Dolphin Conservation Society.
