Fully Funded 4-year PhD opportunity available: Engineering Synthetic Microbial Ecosystems for Deployable Microbiome Modulation
MicroMod Concept: Surface coated Gastrointestinal resistant microparticles which target the growth of beneficial gut bacteria
Project Lead: Esther Gbadebo
Next-generation prebiotics: MicroMods is a precision microbiome-modulation platform based on engineered microcomposite materials that selectively promote the growth of beneficial gut bacteria. Rather than broadly stimulating the microbiome, MicroMods delivers targeted prebiotic compounds within gastrointestinal-inert carriers to support engraftment of specific microbial groups. The project underpins development of a recently filed patent covering this microcomposite-based scaffolding prebiotic technology, enabling translation towards personalised microbiome therapeutics.

Many common oral diseases are caused by an unhealthy balance of bacteria in the mouth, and these diseases can increase the risk of developing other conditions such as cardiovascular disease and some types of diabetes.
Current treatments often rely on broad-spectrum antimicrobials, which can temporarily reduce harmful bacteria but also damage the beneficial microbes needed for long-term oral health, leading to a cycle of continued disease.
Our research aims to develop a new therapy that restores a healthy oral microbial community by delivering “good” bacteria back to the mouth in a controlled and sustained way. By helping beneficial microbes form stable, protective communities (biofilms), this approach could lead to longer-lasting treatments for oral microbiome-related diseases and improve overall health.

Faecal microbiota transplantation (FMT) involves transferring stool from a healthy donor into a patient to restore a balanced gut microbiome. It is currently licensed for recurrent Clostridioides difficile infection, where it achieves success rates of around 90%, exceeding those of antibiotics. These successes have driven interest in applying FMT to other diseases.
One such condition is inflammatory bowel disease (IBD), a chronic disorder affecting over 500,000 people in the UK. IBD includes Crohn’s disease and ulcerative colitis (UC). This project focuses primarily on UC, where current clinical trials suggest greater therapeutic potential for FMT.
The project investigates which therapeutic components (“bioactives”) are present in donor stool and in different FMT formulations, including processed faecal slurry (slFMT) and freeze-dried oral FMT (loFMT). These include beneficial bacteria, bacteriophages, and short-chain fatty acids. It also examines whether these bioactives survive processing and contribute to treatment efficacy, with the goal of developing evidence-based guidelines to standardise and optimise FMT medicine production.
Microencapsulation of Anaerobutyricum hallii as an oral next-generation probiotic
Project Lead: Yijia Zhong
Next-generation probiotics are beneficial bacteria that naturally live in the human gut and have specific health-promoting functions. Many of the most promising candidates are strictly anaerobic bacteria, meaning they cannot tolerate oxygen, which makes them extremely difficult to manufacture, store, and deliver as living therapies.
This project focuses on developing Anaerobutyricum hallii as a next-generation probiotic. A. hallii is a beneficial gut bacterium known to produce important metabolites, including short-chain fatty acids, that support gut health and influence immune and metabolic function. However, its extreme sensitivity to oxygen presents major formulation challenges.

Periodontitis (otherwise known as gum disease) is one of the most prevalent chronic conditions worldwide. Periodontitis results in sore and bleeding gums and is caused by an imbalance that exists within that person's oral microbiome. Beyond bleeding gums, periodontitis can also lead to tooth loss and is implicated in Alzheimer’s and heart disease
The reliance on antimicrobial treatment in Periodontitis fails to fix the root cause, meaning most people will have to regularly return to the hygienist or even experience worsening of the disease.
My research is focused on improving the treatment and prevention of recurring gum disease by addressing this imbalance. My project is working on developing a system that can deliver a healthy oral microbiome (given by a healthy donor) to help restore the balance in the mouth and prevent or delay the return of periodontitis after dental treatment.
Synthetic community model to study AMR in the lab
Project Lead: Nneka Igwebuike
Antimicrobial resistance (AMR) in the gut microbiome refers to the ability of gut bacteria to survive antibiotic treatment and share resistance genes with other microbes. The gut acts as a major reservoir for these genes, allowing resistance to spread between harmless commensals and potential pathogens. This project investigates how microbial metabolites influence the emergence, persistence, and transfer of AMR within gut microbial communities, with the aim of identifying new strategies to limit resistance spread.
