Alexandre Hobeika is a researcher in political science and sociology. He works on the coordination of actors for the governance of health risks, using the One Health approach. He has recently focused on Covid-19, antimicrobial resistance, and African swine fever. During MOOD science webinar, he presented the results of a socio-political study about the relationships between modelers and decision-makers during the Covid-19 crisis, at the national level in Finland and France. While these countries have been affected by and responded to the pandemic in different manners, many reported points of tension between science and policy have been similar: a narrow political framing and governance of the crisis, claims of political instrumentalization of science, fraught debates among scientists. Then he layed out possible avenues for a better preparation of the science-policy collaboration, based on the stakeholders’ feedbacks of these results.
