Your job

The present PhD student position and associated research project is part of the 13 PhD projects of the VIVACE Doctoral Network, funded by the Marie Sklodowska-Curie action of the Horizon Europe programme.

Context on the VIVACE doctoral Network
While outbreaks of highly pathogenic avian influenza viruses (HPAIV) in Europe used to be rare and geographically contained, the situation has dramatically changed in the last few years with thousands of outbreaks reported in domestic poultry and wild birds.

Vaccination of poultry against avian influenza, which used to be prohibited in the European Union (EU) due to trade restrictions, is now being given full consideration, as it is becoming clear that traditional prevention and control approaches alone will not curb the accelerating pace of occurrence of devastating HPAIV epidemics. However, vaccinating poultry does not come without important challenges.
The project VIVACE, gathering 15 leading universities or research institutes and 5 private companies, puts together an ambitious doctoral network to integrate poultry vaccination approaches into efficient management strategies for HPAIV. This interdisciplinary project offers funding for 13 PhD scholarships along the continuum from virology and immunology to spatial and molecular epidemiology, computer sciences and social and behavioural sciences. Irrespective of their background, all doctoral candidates from VIVACE will benefit from a unique international training in these fields, as well as state-of-the-art soft skill development. In doing so, the VIVACE consortium ambitions to train the next generation of scientists with integrated understanding and expertise in avian influenza management.

Description and objectives of the PhD project
Highly Pathogenic Avian Influenza (HPAI) is a serious disease affecting poultry, with significant economic and public health implications. Vaccination and biosecurity measures (e.g., hygiene protocols or restricting farm access) are critical for controlling outbreaks, but not all farmers adopt these measures.
This PhD project investigates the behavioural and economic factors that influence farmers' willingness to vaccinate and adopt biosecurity measures for controlling HPAI outbreaks. The research integrates a survey experiment conducted in the Netherlands and France with quantitative risk assessment approaches.

The project aims to:

  • Characterize farmer preferences and behavioural factors for HPAI-relevant vaccination scheme attributes:
The project explores the factors that make vaccination schemes appealing to farmers. This includes aspects like cost, effectiveness, or side effects of vaccines.
  • Quantify the impact of vaccination uptake on farm biosecurity compliance:
Examine whether farmers who vaccinate are more or less likely to comply with other biosecurity measures, such as disinfecting equipment or restricting visitor access.
  • Assess how vaccination uptake and biosecurity compliance together impact the risk of HPAI outbreaks:
Evaluate the combined effects of vaccination uptake and biosecurity measures on the risk of HPAI outbreaks.

The candidate will collaborate with an interdisciplinary team of researchers in economics, social sciences, and veterinary sciences to achieve these objectives.

Your qualities

We are seeking an enthusiastic and results-driven candidate who meets the following criteria:

  • A successfully completed MSc degree in:
    • Agricultural or business economics, with an interest in animal production; or
