Rate My Professor Christopher Stewart

Professor Christopher Stewart holds the position of Professor of Human Microbiome Research at Newcastle University, within the Faculty of Medical Sciences. He obtained his BSc in Biotechnology with First Class Honors and a PhD in Molecular Microbial Ecology from the University of Northumbria. His career began with research fellowships at Northumbria University, followed by a postdoctoral associate position at Baylor College of Medicine in Houston, Texas. Upon returning to the UK, he advanced at Newcastle University through successive roles including Faculty Fellow, Newcastle University Academic Track (NUAcT) Fellow, Marie Curie Research Fellow, Wellcome Trust and Royal Society Sir Henry Dale Fellow, and 2021 Lister Institute Prize Fellow. His current professorship is supported by the William Leech Charity. Stewart has garnered prestigious awards such as the 2025 Blavatnik Awards for Young Scientists United Kingdom Life Sciences Laureate, 2024 Neonatal Society Rising Star Award, 2023 Applied Microbiology International WH Pierce Prize and NOSTER & Science Microbiome Prize Finalist, 2023 election to the Royal Society UK Young Academy, 2022 Microbiology Society Fleming Prize, and 2015 Microbiome Award for early career researchers.

Stewart's research specializes in the ecology of microbial communities and host responses in human health and disease, with emphasis on early life from neonatal to childhood, particularly preterm infants. He utilizes multi-omic analyses of clinical samples and innovative ex vivo human enteroid co-culture models to investigate microbial-host interactions and gastrointestinal disease mechanisms, including necrotising enterocolitis (NEC). His discoveries highlight how human breast milk oligosaccharides foster beneficial bacteria in preterm guts, suppress pathobionts, and inform probiotic therapies and nutrition strategies. This work drives clinical trials, alters practices in infant care worldwide, and extends to global health initiatives in low-resource settings via novel premature gut organoid models. Notable publications include Chapman JA et al., 'Clostridia from preterm infants metabolize human milk oligosaccharides to suppress pathobionts and modulate intestinal function in organoids' (Nature Microbiology, 2026); Oliver AJ et al., 'Single-cell integration reveals metaplasia in inflammatory gut diseases' (Nature, 2024); and Young GR et al., 'Gut microbiome comparability between DNA extraction kits' (Gut, 2026). Stewart contributes to the Medical Advisory Panel of NEC-UK and participates in public engagement through media and outreach.
