A marine biologist with a focus on tropical coastal management, I have 20 years’ experience of working in integrated coastal zone management with NGOs, public and private agencies in the Caribbean, Eastern Africa and Egypt. I have extensive natural resource management experience as a Manager of a Marine Park and National Park (8 years in the Dutch Caribbean), and project leader for various bilateral research and development projects. Research and monitoring has included environmental, fishery and sea turtle assessments for Protected Areas in the Caribbean, Egypt, Uganda and Nigeria.

As a Researcher and an Environmental Consultant for both the public and private sector, I have produced and coordinated Protected Area Management Plans, targeted Species Monitoring Plans and Environmental Impact Assessments, with an ongoing personal interest in co-management of natural resources, stakeholder engagement within conservation management policies and activities and communication of conservation and research activities to the wider public. My research interests lie in the understanding of spatial and habitat use by marine species, with a focus on sea turtles and reef fisheries, predominantly in the Caribbean and Indian Ocean.

  • BIO000 Foundation Biology

    This module will provide the learner with a detailed and holistic overview of life on earth and includes a range of subject matter including evolution, cell biology, anatomy and physiology, as well as behaviour, ecology and conservation. The module is supported by two practicals that aim to build core skills required within the field of biology including identification skills, field based sampling, and numerical skills.

  • BIO229 Tetrapod evolution

    This module follows on from the introduction of vertebrates in the Level 4 Animal Diversity, Form and Function module, providing detail on form and function in vertebrates that spend all or part of their life cycle on land. Aspects of vertebrate morphology and physiology will be considered in terms of adaptation and evolutionary contraint. Practicals will provide an introduction to the anatomy of birds and mammals by means of dissection, avian flight (specifically the factors that have lead to differences in wing shape and flight performance), and an exploration of how climate affects population level processes in amphibia. Overall, students will gain an appreciation of the diversity of vertebrate types and an insight into the fundamental importance of metabolic rate in animals.

  • BIO327 Tropical marine ecology field course

    This field based module will provide students with an introduction to the ecology of tropical marine systems and teach students the key practical skills required by tropical marine biologists. Students will obtain training in how to design, implement and report scientifically robust marine research. The module will complement the level three marine field course and help develop key skills in field based marine biology. Students will learn skills in marine ecology and taxonomy, in-water marine sampling and surveys, and impact assessment. This module will be mostly practical based but will also include theory lectures, workshops and feedback sessions. It would be structured around seven days of directed practical activities and a three day small group based mini-project. The field course will utilise snorkeling and intertidal walking as the major means of sampling throughout directed practical¿s.

  • BIO330 Tropical marine ecology and conservation

    This module will provide a holistic overview of the ecology and conservation of important marine ecosystems, and will place this information within the context of ecosystem services, and their value to humanity. This module will consist of up to 12 lectures/seminars on the following topics: ¿ Diversity and biology of coral reef communities ¿ Structure and function of seagrass meadows (temperate and tropical) ¿ Mangrove forest ecology ¿ Connectivity across the tropical marine seascape ¿ The ecosystem services of tropical marine systems ¿ Response of coral reef systems to climate change and ocean acidification ¿ Degradation of tropical marine systems ¿ Resilience thinking and the management of tropical marine systems The module also contains a workshop session and additional direct contact with the module lead lecturer.

  • BIOM22 Environmental Assessment and Management

    This module covers Environmental Assessment & Management skills. Students enrolled in this module will learn to choose suitable environmental management systems to solve environmental problems in the real world, to apply a variety of techniques to environmental evaluation, and to make environmental impact assessments and reports. This module introduces the SPICOSA System Approach Framework through stakeholder interaction and construction of conceptual models of ecosystems followed by delivery of the outcomes of these to stakeholders. It aims to give the students an overview of the full process of developing a generic management strategy for a range of natural ecosystems.
