about the lab

I am interested in the ecology and evolution of microbial communities, particularly in the interactions between bacteria and the mobile genetic elements that infect them. Elements such as plasmids and phages play key roles in these communities; acting not only as agents of horizontal gene transfer by carrying with them bacterial genes when they move between hosts, but also as parasites as they exploit their bacterial hosts for their own replication.


In my work I explore how coevolution shapes these interactions and how they, in turn, impact the wider community. You can read more about these projects here


I also love making graphics for publications and beyond so I’m starting a little collection here.


I am currently a NERC Independent Fellow at the department of Animal Plant Sciences, University of Sheffield.


Harrison Lab  Evolution within microbial communities


Its all kicking off! Thanks to the URI Center for Sustainable foods we have funding for an exciting new PhD studentship working with Dr. Anna Krzywoszynska on using temperate phages to improve rhizobial inoculants

The lab grows again. I'm so excited to have nailed down an exciting PhD studentship and and even more exciting student. Grace Wardell will be starting in the autumn working with me, Tim Daniell (Sheffield), Euan James, Pete Iannetta (James Hutton Institute), James Hall (Liverpool) and PlantWorksUK. She'll be looking at the effects of introducing a novel bacteria into microbial communities as the UK embraces Soya production.




The lab grows. Welcome to Sam Ford who is research technicianing with me and Mike Brockhurst. Hes primarily working on a BBSRC project looking at plasmid manipulation in Pseudomonas fluorescens but made the mistake of saying he likes bioinformatics...
