I manage an active research portfolio, including research into Campylobacter global epidemiology, emergence of multi-drug resistant Campylobacter coli, Campylobacter ecology and evolution and Genome-wide identification of transmission and virulence traits. I am a research leader with proven leadership skills and the ability to design administer and articulate a clear research vision and strategy for effective delivery of successful projects.
CAMPYLOBACTER GLOBAL EPIDEMIOLOGY
Driven by collaborative projects in S. America, North Africa and SE Asia – where Campylobacter infection has serious implications for child health and malnutrition. Several smaller, individual collaborative projects in the Gambia, Burkina Faso, Ghana, Benin, Thailand, Peru, Vietnam, Egypt, China, USA, France and India.
EMERGENCE OF MULTI-DRUG RESISTANT CAMPYLOBACTER COLI
Ongoing study with collaborators in Peru who are part of the MAL-ED programme: a global network of researchers investigating child health, including gastrointestinal disease and malnutrition at several establish sites in LMICs.
IDENTIFYING EVIDENCE OF HUMAN ADAPTATION IN BACTERIAL PATHOGENS
Projects in Campylobacter and the human host restricted pathogen, Helicobacter pylori, where a rapidly evolving genome with high levels of horizontal gene transfer allows the reconstruction of recent human migrations to the extent that genetic admixture among the bacteria reflects interactions among human populations.
Finally, I have a track record of successful supervision of postdoctoral research staff and/or postgraduate students. I have supervised technical research staff, visiting researchers and undergraduate/ postgraduate students since 2012
I’m part of the MRC CLIMB consortium that provides high-performance computing infrastructure to UK microbiologists (2015 – present), which has included organizing workshops in Brazil, the Gambia, Vietnam and the UK.
