My Work

My group is interested in viruses. We study how viruses interact with the immune system inside the body, both in humans and animals. We are also interested outside the body how viruses can persist, can move between hosts and how behaviours, therapies and vaccines can influence the evolution of the virus and its spread. Viruses such as RSV, coronaviruses and influenza are of particular interest. Separately, I work with the UCD One Health Centre to improve our understanding of One Health and how a One Health approach can be more effectively operationalised.

Potential Projects

I am open to ideas, but here are some potential projects:
1.
How are therapies and vaccination impacting RSV in humans on the island of Ireland? With the introduction of new anti-RSV immunotherapies and vaccines on the island of Ireland, I am interested to understand their impact. Have they reduced incidence of disease? What is the uptake like? Collect samples, sequence them and model virus evolution overtime - how is the immunisation programme impacting on what is circulating? Collaborate with colleagues in Northern Ireland to do the same thing. They are vaccianting rather than immunising - is that affecting patterns?

2.
Comparative Pathways to Operationalising One Health: A Cross-National Study of Systems Integration in Ireland and other countries or regions.
Hypothesis:
While the One Health approach is globally endorsed, its operationalisation is context-dependent. Cross-sectoral integration varies significantly due to differences in governance structures, institutional capacity, political will, and socio-ecological realities. Comparative analysis can reveal transferable strategies and contextual enablers that drive effective One Health implementation.
Main Research Question:
How do differing national contexts shape the operationalisation of One Health, and what lessons can be learned from a cross-national comparison to inform more effective, locally grounded, and globally relevant One Health strategies?

Emerging Supervisor

I would aim to identify co-supervisors that would bring benefit to the project, from different disciplines.
