Greg is a post-doctoral researcher at Northumbria University with a background in clinical microbiology. He completed a BSc in Biomedical Science in 2014, during which time he gained experience working in an NHS lab. Greg achieved his PhD in molecular microbial ecology in 2017, focusing on utilising molecular, genomic, microbiological and bioinformatic methods to investigate the acquisition and longitudinal development of microbial communities in clinical settings. 

Since then the scope of Greg's research has expanded to include several projects investigating host-associated and environmental microbiota and how specific interventions can shape or manipulate microbial communities for desired outcomes.  

Greg has shared his research by publishing in peer-reviewed journals, contributing to chapters in text-books and presenting at international conference events.
