Maria Xiridou works on mathematical modelling of sexually transmitted infections, such as HIV, gonorrhoea, chlamydia, hepatitis B, and monkeypox. She is interested in understanding infectious disease dynamics and how these can be influenced by behavioural changes and public health interventions. Maria has worked on the impact and cost-effectiveness of PrEP and antiretroviral therapy for HIV; risk-group and universal hepatitis B vaccination; antimicrobial resistance in N. gonorrhoeae, the monkeypox outbreak, and the impact of the COVID-19 pandemic on chlamydia, gonorrhoea, and hepatitis B virus notifications. 


Maria Xiridou studied Mathematics at the University of Ioannina, Greece, and Operations Research at  Columbia University, USA. She obtained her PhD at the University College London, UK, on stochastic models for tuberculosis transmission and control. In 2001, she started working at the Municipal Health Service of Amsterdam on modelling HIV transmission dynamics.

She works at the Centre for Infectious Diseases Control of the RIVM since 2006.
