Professor Noel Mc Carthy

Professor of Population Health Medicine (Public Health & Primary Care)


Noel McCarthy is Professor of Population Health Medicine at Trinity College Dublin. His principal research focus is on infectious disease epidemiology with broader interests applying research methods to public health problems. His teaching goal is to facilitate students to learn by thinking and reflective experience, whether that be specific and technical such as how to think as an epidemiologist, or more general such as reflecting on how power structures in a society affect the distribution of health and wellbeing. He qualified in medicine from Trinity in 1989, completed general internal medicine training Dublin and Cork before moving into infectious disease and public health and working internationally. This included refugee healthcare work in Africa with Médecins Sans Frontières, microbiology (St James's), field epidemiology training in Sweden, and work at the Food Safety Authority of Ireland before training in public health in the UK specialising in communicable disease control and infectious disease epidemiology with clinical posts as a consultant in communicable disease control and National Infection Service epidemiologist. Research training included an MSc (Medical Statistics) at the University of London and Wellcome Trust Fellowship supported DPhil at the University of Oxford integrating population genetic analyses in the epidemiology of bacterial disease (Campylobacter) supervised by Martin Maiden. Academic posts have been as a research fellow at the Department of Zoology, University of Oxford and Professor of Communicable Disease Control Epidemiology at Warwick Medical School.

Research interests have focused on the integration of pathogen genetic data in infectious disease epidemiology, developing and applying novel epidemiological approaches in communicable disease control, using routinely collected data for research, and a broad range of work linking research into public health practice. Research contributions in these areas are outlined below. The development of an approach to source attribution of pathogens to zoonotic reservoirs applying population genetic algorithms using the example of Campylobacter infection [PMC2063414] with subsequent validation [PMC3988352] and application to human infection [PMC2916502]. This has become a standard approach as recently reviewed [PMC6820127] including in national monitoring projects in the UK. Integrating bacterial genome sequence data with other epidemiological data including developing and validating core genome multi-locus sequence typing [PMC5483910] for outbreak detection in population level surveillance [PMC3719633], ad hoc application studies such as the emergence of an STEC clone [PMC6256402](7) investigating care setting streptococcal [PMC4880081] and milk-borne Campylobacter [PMC4551004] outbreaks, population studies of the distribution of TB transmission [PMC4571080], and the ecology of Campylobacter as it relates to human infection [PMC3487483]. Reviewing the use of approaches using the multi-locus sequence typing paradigm in epidemiology [PMC3980634]. Developing novel epidemiological approaches in applied infectious disease epidemiology such as: describing case-case comparisons based on bacterial subtypes [PMID: 10480708] which is now widely used (a "case-case" and "infection" search in Google Scholar returns over 9,000 items); applying classical epidemiological studies to the food supply chain in outbreaks [PMC6053626]; validating temporospatial approaches to detecting smaller outbreaks [PMID: 24690264]; the use of internet panels for controls in outbreak investigation [PMC5848756]; and the use of modelling approaches to evaluate disease control interventions [PMID: 21859502]. Diverse collaborative work includes contributions to vaccine trials [PMID: 26165918], evaluation of the herd immunity effects of childhood vaccination [PMID: 27955789] with direct policy implications for adult vaccination policy and basic science work on Campylobacter [PMC18403712].
