Professor Simon Milling

Professor of Immunology (Immunology),
Associate - Life Sciences (School of Life Sciences)

Professor Simon MillingMy lab works on the biology of the dendritic cells in the intestine, and on how these cells respond to infectious or inflammatory stimuli. We study the functions of dendritic cell subsets in vivo, using samples from mice and from people. Using blood and tissue samples from people with intestine-associated inflammatory disease, we also aim to understand the contributions of immune cells to pathogenesis, in order to improve future treatments. Currently we use samples from people with inflammatory bowel disease, psoriatic arthritis, and autoimmune alopecia. The aim of all this work is to understand the vital roles that intestinal immune cells play in the induction and polarisation of adaptive immune responses against pathogens, and how these responses also contribute to disease when they are not properly controlled.

Dr Richard Hansen

Consultant Paediatric Gastroenterologist

Dr Richard HansenMy main research interest is the gastrointestinal mucosal microbiota and its importance in paediatric disease, particularly inflammatory bowel disease. I am particularly interested in the molecular characterisation of the microbiota and its subsequent modification for the purposes of therapeutic effect.

This theme of microbial therapeutics fits nicely into the concept of stratified medicine since the microbiota is highly individualistic yet also modifiable. Being a paediatrician, I am naturally interested in how the gut microbiota develops as the child grows and matures, particularly at the earliest stages of microbial colonisation. This area of research is a natural extension of my CSO-funded PhD studies during which I was the first to catalogue and publish the colonic microbiota in paediatric IBD at the onset of disease.

I currently hold a competitive fellowship supporting the development of microbial therapeutic studies, awarded by NHS Research Scotland. In addition to my research interests, I have clinical interests in paediatric inflammatory bowel disease, liver disease and Helicobacter pylori. I am clinical lead for paediatric hepatology and paediatric endoscopy training in the West of Scotland and am the Scottish endoscopy representative on British Society of Paediatric Gastroenterology, Hepatology and Nutrition.

I helped co-host the 2017 meeting of British Society of Paediatric Gastroenterology, Hepatology and Nutrition and the 2019 meeting of European Society of Paediatric Gastroenterology, Hepatology and Nutrition in Glasgow.

BINGO Group Collaborators

Professor Christine Edwards

Professor of Nutritional Physiology (Medicine), Associate (Institute of Health and Wellbeing)

Phot of Professor Christine EdwardsChristine Edwards is Professor of Nutritional Physiology in the School of Medicine, Dentistry and Nursing at the University of Glasgow where she has worked for 28 years. She trained at the University of Sheffield with a BSc in Biochemistry and Physiology and in her PhD developed one of the first continuous culture models to study the human colonic microbiota and the impact of diet and environment on bacterial metabolism. She worked as a post doc in Sheffield University studying gut function, motility and short chain fatty acids. She then worked at Edinburgh University studying the gut microbiota and their role in the health effects of dietary fibre and resistant starch before moving to the University of Glasgow as a Lecturer in 1990.

In Glasgow, she focused on early bacterial colonisation of the infant gut and the role of environment and early diet, funded by two multi-partner EU grants (MEDIGUT and INFABIO) of which she was the co-ordinator.

She then studied the role of gut bacteria and carbohydrate substrates in Crohn’s disease, obesity and human metabolism. Her current work funded by the BBSRC Manipulating the activity of the gut microbiota with fermentable carbohydrates to maximise the bioavailability of bioactive phenolic acids for health. This project is studying the interactions of dietary fibre and plant polyphenols (often consumed together) on bioactive molecules such as SCFA and phenolic acids released by the colonic microbiota. She is also a co-investigator for a MRC GCRF project, in Malawi studying Development of nutritional strategies for diabetes prevention in Malawian adults at high diabetes risk. In addition, she is leading an ILSI Europe working group to evaluate the evidence for the transfer of bacteria from mother to infant through the placenta and via the breast milk microbiome


Dr George Raptis

Consultant in Paediatric Allergy and General Paediatrics, Honorary Clinical Senior Lecturer

Photo of Dr George RaptisDr George Raptis is an Honorary Clinical Senior Lecturer and Consultant in Paediatric Allergy, based at the Royal Hospital for Children, Glasgow. George's main interest is to understand further the pathophysiology of gastrointestinal allergy in children. Better understanding of the microenvironment of the gastrointestinal mucosa and mechanisms of allergy will enable researchers and clinicians to develop means to prevent or induce immunological tolerance. Additionally, he is striving to develop a model of care for allergic patients that aims to consider each stage of the allergic disease continuum and propose a number of strategies to provide consumer-focussed, best care. Dr Raptis is committed to contributing to the development of research in this field in order to alleviate the impact of allergies on sufferers.

Dr Donal Wall

Senior Lecturer (Bacteriology) Associate (School of Life Sciences)

profile picture of Dr Donal WallMy lab works on interactions between bacteria and their hosts, primarily focusing on the mammalian intestine. We focus on all aspects of bacterial pathogenesis from mechanisms of intracellular bacterial survival, their control of programmed cell death in host cells and immune response to pathogen presence.

Our interests intersect very well with those of the BINGO group as we focus on Escherichia coli pathotypes associated with Crohn’s disease. These studies have focused on the origin of these strains, the potential input of Western food production methods into their evolution, and their role as drivers or bystanders as disease progresses. Membership of the BINGO group has facilitated progression of these studies beyond the bench to provide clinical relevance to our findings.

More recently we have begun to focus on the role of bacterial metabolites from the Crohn’s disease intestine in secondary health problems associated with the disease. Where possible and necessary we have applied advanced technologies such as RNA sequencing, mass spectrometry imaging and mass cytometry imaging to understand these complex host-microbe interactions. This work is carried out in collaboration with Dr. Richard Burchmore from Glasgow Polyomics and Dr. Richard Goodwin from AstraZeneca.
