All life depends on interactions with microscopic organisms. These interactions facilitate thousands of different organisms to communicate and have an impact on the whole ecosystem in both positive and negative ways. The use of, now commonplace, sequencing technologies has revolutionised the field of microbiology, but it is the ecology of these organisms that will allow us to understand what they are doing.
It is an exciting time to study microbial ecology. With the ever increasing technological advances we are now getting unparalleled amounts of data through which we can craft theories that underpin life on Earth. We can also use the knowledge of theory to tackle pressing issues such as the rise of antimicrobial resistance, pressures on food production, the progression of infectious disease, and rewilding of “lost” habitats.

As a microbiologist and ecologist, I have a directed interest in how microbial species communicate (in terms of public goods and horizontal gene transfer) and are able to persist in highly diverse communities. This question allows me to combine experimental microbiology with next generation sequencing to go beyond simply surveying the diversity, and understand functional processes underpinning the community dynamics.
I currently utilise experimental microbial systems to investigate mechanistic processes that determine the survival of bacterial species within varied communities. This combines various “omic” approaches with the more traditional culture approach to understand the role this diversity plays in the wider functioning of the communities.
Many questions remain unanswered in microbial ecology; general, reproducible data that tests wider-ecological theories is paramount. To achieve this I use a wide variety of samples from rain-filled pools amongst the roots of trees to plant associated soil, and even sputum expectorated due to respiratory disease. This way I can ask both fundamental and highly applied questions of my data.
I currently have collaborations with institutions both here in the UK and aboard:
