Biography
I am a microbiologist by training with specific research interests in the bacteria that inhabit the gastrointestinal tract of mammalian hosts.
After receiving an undergraduate degree in Microbiology from the University of Aberdeen I studied for my PhD at the Rowett Institute and at the University of Dundee, specialising in gut microbiology and the role that intestinal bacteria play in the breakdown of dietary fibre. I then spent eight and a half years at the Wellcome Sanger Institute in Cambridge, a renowned centre for genomics research. While there I used state of the art DNA sequencing facilities to better characterise host-associated microbial communities and shed light on the roles these microbes play both in health and in diseases such Cystic Fibrosis, inflammatory bowel disease and infection with Salmonella spp. and Clostridium difficile.
I am now a Senior Research Fellow/Principal Investigator at the Rowett Institute within the University of Aberdeen. In our lab we combine anaerobic microbiology with DNA sequencing technologies in order to examine interactions between host diet and the intestinal microbiota of humans and animals, and how these factors may contribute to host health.

Research Overview
Microbiota research has been revolutionised in recent years by the advent of modern DNA sequencing technologies. These allow large-scale, in-depth studies, greatly expanding our ability to monitor the microbiota and how it responds to host behaviour such as changes in diet. However, traditional microbiology techniques such as anaerobic culture also remain highly relevant, and help us to understand the functional roles that individual members of the microbiota may play in the intestines. In our lab we combine DNA sequence analysis and microbiological approaches to generate novel insights into the intestinal microbiota of humans and animals.
Current Research
Much of our current research interests are in identifying key functional groups of bacteria within the intestinal microbiota of humans and animals. Although intestinal microbiotas are extremely complex entities, with many species sharing overlapping functional capabilities, it is thought that some deleterious or beneficial activities are limited to a relatively small range of species. In particular, we are interested in microbial contributors to the development of chronic ailments. For example, we are interested in bacterial consumers of lactate, accumulation of which has been linked to chronic diseases such as inflammatory bowel disease, and producers of trimethylamine (TMA), which has been linked to cardiovascular disease. We are also interested the role that host diet plays in the prevalence and activities of these key functional gut bacterial groups.
In addition, we study the role that the intestinal microbiota plays in inhibiting pathogenic microbes. We use the Rowett Institute's extensive collection of gut bacteria to screen for individual strains that show activity against a range of important pathogens of humans and animals. We are also members of the EU-funded FunHoMic network, as part of which we are particularly interested in identifying specific microbes, and mechanisms, involved in antagonistic activity against the fungal pathogen Candida albicans in the colon.
We are also part of GCRF-funded Action Against Stunting Research Hub, which involves partners from many different countries, where we are carrying out research to investigate how the microbes that are present in the intestines of children in low to middle income countries might play a role in their risk of developing stunting.
Ultimately, the unifying goal across all of these projects is to determine key functional groups of gut bacteria, which is a critical step towards developing microbiota-based therapeutics for use in humans and animals.
