I am a Ph.D. candidate in Oceanography with several years of experience in biological research of marine ecosystems, working primarily in the fields of Arctic Marine Ecology and Population Dynamics. I am also highly interested in the potential effects of climatic change on marine habitats and biodiversity.


  • Conducting fieldwork in a variety of marine settings, including logistically challenging environments, using a wide range of sampling methodologies
  • Analysing marine specimens in the laboratory to collect and collate information on their ecology
  • Communication of science to a wide range of audiences via a range of media
  • Writing comprehensive scientific publications utilising a range of software applications
  • Managing teams to ensure that collective contributions are maximized for successful project outcomes

Extensive laboratory experience analysing a diverse range of marine organisms (e.g. identification, staging, measuring and photographing). Animals investigated range from plankton to sponges to fish. Development of novel methods and stains for zooplankton feeding and maturation studies. Vast experience of methods used to filter the chemical and biological constituents of seawater. Conducted experiments to observe feeding in chaetognaths and zooplankton fecal pellet production. Experience in zooplankton lipid extraction and fatty acid trophic marker analyses.


Broad experience working on several Arctic research ships (in Norway and Canada), sampling the pelagic, benthic and under-ice realms, over timeframes of weeks to months. Extensive field experience from plankton ecology studies in Arctic and temperate waters, and work on rocky and sediment shores in the UK. Deployment of many zooplankton sampling instruments including nets and cameras. Qualified in Fall Protection Awareness for ship safety (June 2013).


Extensive use of the RTM and MinitabTM statistical software environments, Microsoft Office (Word, Excel, Access, PowerPoint). Ocean Data View for marine map building, Ecopath with Ecosim for addressing specific modelling questions, and hardware and software associated with the Lightframe On-sight Key-Species Investigation System (LOKI) for in situ imaging of zooplankton.
