I am a research officer on the EU-funded (Horizon 2020) SponGES project, which aims to develop an integrated ecosystem-based approach to preserve and sustainably use vulnerable deep-sea sponge ground ecosystems of the North Atlantic. Prior to this, I supported research activities associated with the BRITICE-CHRONO (British Irish Ice Sheet Chronology) and CLAM (Climate of the LAst Millennium) projects as research technician, and worked for an oceanography consultancy. I completed my Ph.D. in physical oceanography at Bangor University in 2015. My research examined tidal effects on the temporal behaviour, quantity, and quality of light reaching the seabed, and their implications for benthic macroalgae. My educational background is in physics and ocean sciences.  


Research Interests

My research interests fall at the interface between physical oceanography and marine ecology, and I am particularly interested in how physical oceanographic phenomena influence the distribution of benthic species (and any feedbacks that may occur). As a sea-going marine scientist with both observational and modelling capabilities, I measure physical parameters at sea, relate these to the presence (or absence) of a given benthic species, and work with mathematical models to develop our best understanding of how these abiotic factors might control the species’ distribution.
