Kathleen M O'Reilly

I am an epidemiologist who specialises in the use of statistical and mathematical models for infectious diseases. My current interests are in polio eradication, norovirus, and vector-borne viral diseases. My research team are the modelling partners of Unicef within the Global Polio Eradication Initiative. We carry out analysis and modelling to better understand epidemiology and inform policy decisions. My current collaborations involve close interaction with the WHO, BMGF and UNICEF to support the final stages of polio eradication such as understanding the effectiveness of vaccination campaigns and developing suitable strategies for response to vaccine-derived polioviruses. Further, I am part of the exciting Noropatrol grant where I am using analysis and modelling to understand and predict why norovirus variant emerge. More recently, I have joined the UK Joint Biosecurity Centre to support analysis and expansion of wastewater surveillance to inform SARS-CoV-2 epidemiology.
