Research interests

My interests are in infection, biofilm formation, antimicrobial development and antimicrobial resistance. I also have some involvement through my PhD project with materials science and surface chemistry. 

PhD project title: "Development of a novel antibacterial silver nanocoating to protect patients from bioaerosol infections in hospitals"


Healthcare-acquired infections (HCAIs) and antimicrobial resistance (AMR) are leading priorities for the National Health Service (NHS) in the United Kingdom. A source of HCAIs in hospitals is the sanitary plumbing system (SPS), for example sink traps and U-bends on hospital wards. Bacteria in these environments form biofilms, complex polymicrobial communities which secrete extracellular polymeric substances (EPS) to lend protection and promote persistence, while also facilitating horizontal gene transfer (allowing spread of antibiotic resistance genes). Biofilms release bacteria naturally and when physically disrupted; these released bacteria can be transported away from the initial biofilm by formation of airborne particles such as droplets and bioaerosols. Upon exposure to patients, particularly vulnerable or immunologically compromised individuals, these bacteria can cause morbidity and mortality. Metal nanoparticles (NPs) offer a potential solution to the problems of bacterial surface colonisation and biofilm formation due to their intrinsic antibacterial and antibiofilm activity, potentially greater longevity and efficacy compared to traditional disinfectants, and ability to be applied to surfaces as an antimicrobial nanocoating. In my PhD project, I aim to develop a method for applying antimicrobial nanoparticles as a coating to relevant polymers, assess this nanocoating for its antibacterial and antibiofilm properties in vitro, and later conduct in situ testing of the nanocoating in real-life hospital environments.

Other research

I have previously completed the following research projects:

  • "Live and heat-killed lactobacilli and their DNA modulate pro-inflammatory cytokine responses in differentiated macrophages" with Dr Andrew Foey (MSc project; 2017-2018).
  • "Investigating mosaic tetracycline resistance genes with further analysis of a potentially novel mosaic" with Dr Philip Warburton (undergraduate dissertation project; 2016-2017)
  • "How do neural stem cells wake up? An investigation of potentially involved molecular signals" with Dr Claudia Barros (Summer research studentship; 2015).
