PhD candidate in Zoology at Trinity College Dublin with Dr Andrew Jackson, Dr Nick Payne and Dr Ian Donohue. My research focuses on the ecology and conservation of elasmobranchs. Projects include: a theoretical study of the variation in trophic niche from isotope analysis among and within individuals; a study of blue shark feeding ecology in Irish waters using biologging & biochem methods; and a socio-economic study of the links between the sport angling industry and conservation in Ireland.

  • In this position, I was in charge of setting up meetings with randomly selected small fishers from three maritime quarters for surveys about the economic health of their fishing business. I collected various pieces of information such as their annual revenue, maintenance costs or other operating expenditures related to their business.

Coexistence of ecologically similar species occupying the same geographic location (sympatry) poses questions regarding how their populations persist without leading to competitive exclusion. There is increasing evidence to show that micro-variations in habitat use may promote coexistence through minimizing direct competition for space and resource...

Gelatinous zooplankton are important predators, prey, and nutrient conduits within marine ecosystems. Information obtained from jellyfish stable isotope compositions can be invaluable to biological and environmental research and management. Protocols for best practice in preparing jellyfish for stable isotope analysis, however, require standardisat...


Question (1)
Would anyone have any recommendations on what the best treatment would be for samples that I am hoping to analyse for pheromones? Is freezing enough? Any recommendations welcome.
Thank you!
