I lead the foodborne enteric pathogen group at the LSHTM where we study the physiology and pathogenesis of Campylobacter (most common bacterial cause of human gastroenteritis in the world) and other related enteric microorganisms (e.g. Listeria spp. and Vibrio spp.). Importantly, we translate our fundamental microbiological knowledge to real life settings by implementing intervention and control strategies. My group uses classical molecular microbiology techniques, and links bioinformatic skills to apply cutting-edge omics based approaches e.g. genomics, transcriptomics and metagenomics to answer relevant research questions.

Research

I lead the foodborne enteric pathogen group at the LSHTM where we study the physiology and pathogenesis of Campylobacter (most common bacterial cause of human gastroenteritis in the world) and other related enteric microorganisms (e.g. Listeria spp. and Vibrio spp.). Importantly, we translate basic microbiological knowledge to real life settings (i.e. by implementing intervention strategies). My group uses classical molecular microbiology techniques, and links bioinformatic skills to apply cutting-edge omics based approaches e.g. genomics, transcriptomics and metagenomics to answer relevant research questions.

Current basic research themes for studying Campylobacter and other enteric microorganisms include: -
- Mechanisms of response to environmental and host stress
- Prevalence and characterising the function of Type VI Secretion Systems (T6SS)
- Survival and persistence mechanisms in relation to host cells; the unfolded protein response
- Mechanisms of adhesion and invasion
- Role of outer membrane vesicles

Current translational research relating to intervention and control strategies include: -
- Understanding the host microbiome and why pathogens such as Campylobacter appear and persist within avians
- The food chain and points of control e.g. analysis of Listeria outbreaks
- Effective management practices
- The role and impact of natural antimicrobials
