Sharon is a Lecturer in Animal Science with the remit of teaching undergraduates and postgraduates (75% in Welsh and 25% in English; funded by the Coleg Cymraeg Cenedlaethol). As well as a teaching role she leads a research group focussed on understanding the functionality of the rumen gut microbiome with the ultimate goal being to increase ruminant nutrient use efficiency and product quality. Alongside the rumen-focussed research her group are involved in investigating the lung microbiome in disease status, and prospecting metagenomic libraries (rumen libraries and those made from other bacterial ecosystems) for enzymes important to the biotechnology industry. Genomics, metagenomics and metatranscriptomics alongside bioinformatics are central techniques used by her group in order to deliver a fundamental understanding of these ecosystems. Sharon also works with many industrial partners to ensure application of some of the research outcomes. She also represents IBERS as part of the rumen microbial networks consortia led by AgResearch, New Zealand.
