We are recruiting a full time 24-month post-doctoral research fellow at the Université Clermont Auvergne and LAPSCO CNRS (Clermont-Ferrand, France) to study the development and dynamics of interpersonal trust in hazard-prone environments. This position will involve fieldwork outside Europe, likely in Ecuador and/or Peru, with populations living near active volcanoes.

Who I am

My name is Guillaume Dezecache. The phonetics is [ɡijom] [dø-z-œf-kæʃ]. I am not offended at mispronounciations.

I am Assistant Professor at the Université Clermont Auvergne, and Researcher at the LAPSCO CNRS. I also contribute to academic research with the Clermont Risk Center. See my CV for information on previous roles.

Research-wise, I also collaborate with the Crowd Cognition group, and I am a proud project member of the Atlas of Comparative Cognition.

Besides these academic roles, I engage in applied research with /S/CITY and the ACTE-lab.

My research is about 'social cognition in extremis' or how life in dangerous and/or resource-scarce environments shapes (and has shaped) our behaviour and social cognitive traits.

I also work on:

  • animal communication and 'animal linguistics' (sensu Schlenker et al.'s)

  • the evolution of emotional communication, emotional contagion and mimicry

  • group and crowd cognition
