I am a highly motivated professional in marine science with 9 years’ experience. I have worked mainly with seaweeds – kelps, and marine invertebrates - crustaceans and bivalves. I have worked in different Universities in collaboration with companies from Europe, New Zealand and Chile in a range of subjects: aquaculture, biotechnology, biochemistry, and physiology. 

I am presently the Module coordinator of:
BIO 003 Laboratory Skills
BIO 004 Molecular Biology and Biochemistry

I am co-supervising a master and a PhD student:
Title: Advanced Land-based Macroalgal Aquaculture (ALMA)
Degree: Masters
Student name: Camilla Norris
Lead supervisor: John Griffin
Institution: Swansea University
Funding: KESS

Title: Establishing the knowledge base for sustainable seaweed cultivation
Degree: Ph.D.
Student name: TBC

  • BIO008 Laboratory Skills

    The module will introduce essential practical laboratory skills. The syllabus is split into three main sections comprising up-to-date training in laboratory safety, basic chemistry and commonly used laboratory procedures. Training is provided through a combination of e-learning, face-to-face teaching, demonstration and hands-on participation. Learners will develop the confidence and tools they need to work safely and effectively in a modern laboratory environment.

  • BIO009 Molecular Biology and Biochemistry

    The module provides an introduction to the identification and role of essential macromolecules within a cell and their basic biochemical processes. Students will also gain a theoretical understanding of the basic concepts of molecular biology of the cell and the practical application of basic molecular techniques. The module will be delivered through a combination of e-learning, direct teaching, demonstration and practical work.

  • BIO108 Molecular and Evolutionary Biology

    ¿Nothing in Biology makes sense except in the light of evolution¿ was the title of a 1973 essay by the evolutionary biologist Theodosius Dobzhansky. The module links fundamental understanding of molecular processes in the cell to principles of genetics and inheritance to a broader appreciation of evolution and how it shapes the natural world around us.

  • BIO335 Fisheries and aquaculture

    This module provides an introduction to the operation and management of commercial fisheries with particular relevance to the current over-exploitation and decline of most commercial fish stocks, and the potential for changing this situation by using aquaculture

I have been involved in 5 Research Projects funded by the European FP6, FP7  and Horizon2020 funding schemes, and 4 projects funded by Research Councils in Portugal and the UK. I have collaborated with 11 research institutions, 24 companies and 9 associations from 11 countries globally. My research mainly focuses on food safety and security, and the blue economy. I have authored 18 scientific publications.

Presently I am interested on the development of sustainable production systems for marine macroalgae and animals. I am mostly interested in integrated multi-trophic aquaculture (IMTA). The basic concept of IMTA is the farming of several species at different trophic levels, that is species that occupy different positions in a food chain. This allows one species’ uneaten feed and wastes, nutrients and by-products to be recaptured and converted into fertilizer, feed and energy for the other crops (Chopin, 2012). As an example we can combine, the cultivation of fed species (finfish or shrimp) with inorganic extractive species (seaweeds or aquatic plants) and organic extractive species (oysters, mussels and other invertebrates). You can learn more about IMTA on my TedEd lesson here (http://ed.ted.com/on/H7rUYhKF)
