I am an ARIES DTP PhD Student at the University of Plymouth, based in the Deep-Sea Conservation Research Unit (DeepSeaCRU) and the Marine Conservation Research Group. My PhD focuses on providing the first estimates of the role deep-sea animals play in the blue carbon budget using a range of lab, deep-learning, and modelling techniques. I hope to quantify the organic carbon content of selected deep-sea species, apply deep-learning techniques to deep-sea image and video analysis to generate species density datasets, model the density of species at the Atlantic basin scale, map the spatial distribution of carbon sinks and assess the efficacy of existing Marine Protected Area networks.

I am also a member of Challenger 150 and the Deep Ocean Observing Strategy DOERs Programme.

Previous work includes mapping vulnerable marine ecosystems across UK & Irish waters using habitat suitability models, developing density-based models of VME indicator species, investigating the role of internal waves in shaping the distribution and density of sponge aggregations, and working on ICES Working Group on Deep-water Ecology.
