Research Interests

I am a plankton ecologist with interests in zooplankton population dynamics, feeding ecology, sources of mortality and the effect of climate change on zooplankton distributions and ecology. I completed my PhD on the population dynamics and importance of mortality in the key marine copepod Calanus helgolandicus at Plymouth Marine Laboratory (PML) in the UK. I interrogated the station L4 marine time-series (now spanning 30 years) from the western English Channel to investigate seasonal and temporal variability and to understand the balance between births and deaths. I focused on the importance of different sources of mortality, including non-predator (using vital stains to distinguish between live and dead copepods) and predator (via molecular gut content analysis to determine gelatinous zooplankton predators of C. helgolandicus). My postdoctoral research will build on these molecular biology techniques (metabarcoding, Next Generation Sequencing, high-throughput sequencing) to develop and implement DNA-based approaches to understand the zooplankton feeding ecology of British Columbia coastal waters – basically to understand what eats what!


I’m a late returner to science research! After my undergraduate studies I worked for the UK Environment Agency for ~10 years (as Pesticides Scientist, Human Health Scientist, Marine Scientist, Climate Change Scientist), but I felt very far away from real science and so I followed my heart and went back to university to do a Masters in Marine Biology from Bangor University, Wales. Before I started my PhD I worked as a research assistant in the Department of Biomimetics, University of Bath, UK, working on fish movement and behaviour. All this science fanned the flames of my interest in marine science and I started my PhD at PML in 2012, graduating in Dec 2017. Short contracts at PML (freshwater phyto- and zooplankton ID and a meta-analysis of marine climate change model outputs), were followed by a month-long research cruise (research assistant) on the Polarstern in the Arctic. September 2018 brought me to UBC for my first postdoc.
