Research interests
I am an early career fisheries researcher/ aquatic ecologist in HIFI. I am interested in how inland fisheries contribute to global food security and also in the gathering and dissemination of fisheries statistics.
I am also interested in the environmental footprint of inland fisheries and other food production sectors and as part of I created a model that estimated the additional water requirements of replacing inland fisheries with other food sources.
I am also invlved in the conservation of fish species in the UK, where I am a trained IUCN regional assessor and help conduct the first IUCN assessment of freshwater fish in Britain, as well as the Favourable Conservation Status for several species.
I also have extensive fieldwork experience carrying out fisheries and environmental assessment.
