The theme of WCE2024 is “Epidemiology and complexity: challenges and responses” which will engage the full depth and breadth of methods and practice in contemporary epidemiology. The meeting will feature top-calibre invited speakers presenting plenary lectures, workshops and interactive sessions. The abstract-driven programme will include oral and poster presentations including theory and application from every sub-discipline of epidemiology. With more than 1000 delegates expected, WCE2024 promises to be a unique opportunity to share experiences and expertise – the opportunities to learn, grow and network within the field will be phenomenal.
