Dr Ozan Gundogdu


Assistant Professor


Keppel Street
United Kingdom


I joined the LSHTM in 2004 as a dual qualified bioinformatician and microbiologist. Before joining the School, I completed a BSc Honours in Molecular Biology followed by an MSc Computer Science (Commendation), both at the University of Hertfordshire. My undergraduate also contained an industrial placement year which was completed at RAFT - Institute of Plastic Surgery, where I was research assistant in the Molecular Biology group.

I completed my PhD in 2011 studying the microbial pathogenesis of Campylobacter jejuni and then completed a two-year Bill & Melinda Gates Foundation funded Post-Doctoral researcher investigating pit latrine characteristics using metagenomics based applications within the Department of Disease Control, LSHTM.

I have since become an Assistant Professor and study the physiology and pathogenesis of Campylobacter (the leading human foodborne pathogen) and other related enteric microorganisms (e.g. Listeria spp. and Vibrio spp.) and importantly to try and translate our basic microbiological knowledge to real life settings (i.e. by implementing intervention strategies). I do this using classical molecular microbiology techniques along with cutting-edge omics based approaches e.g. genomics, transcriptomics and metagenomics.

I currently supervise four PhD students and supervise MSc research projects at the LSHTM (ten students since 2006).


My research interests and vision are to study the physiology and pathogenesis of Campylobacter (the leading cause of bacterial enteritis worldwide), and other foodborne enteric pathogens (e.g. Listeria spp. and Vibrio spp.) and importantly to try and translate our basic microbiological knowledge to real life settings (i.e. by implementing intervention strategies to reduce Campylobacter within the food chain). Over the past 16 years, I have utilized classical molecular microbiology techniques, and linked my bioinformatics skills to provide cutting-edge omics based approaches such as genomics, transcriptomics and metagenomics in his research (41 peer reviewed manuscripts).

Current basic research themes for studying Campylobacter and other enteric microorganisms include: -  

  • Mechanisms of response to environmental and host stress
  • Prevalence and characterizing the Type Six Secretion Systems (T6SS)
  • Survival and persistence mechanisms in relation to host cells; the unfolded protein response
  • Adhesion and invasion properties
  • The 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
  • The food chain and points of control e.g. analysis of Listeria outbreak strains
  • Effective management practices
  • The role and impact of natural antimicrobials

In relation to Campylobacter, I have completed the full re-annotation of the C. jejuni NCTC11168 genome (in collaboration with the Sanger Institute) and have created and run the Campylobacter Resource Facility (CRF) website.
