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 of Social Cognition at the Université Clermont Auvergne, and Researcher at the LAPSCO, a CNRS research unit based in Clermont-Ferrand, France. I am also involved in the 'Disaster' research program of the CAP2025 initiative. 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.

Teaching-wise, I am also Faculty Member of the Open Mind cognitive sciences Master programme of the University of Bucharest, Romania.

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

Research

My main research theme is on 'social cognition in extremis' or how organisms behave socially when they live in dangerous and/or resource-scarce environments.

I am also involved in projets on:

  • animal communication and 'animal linguistics' (sensu Schlenker et al.'s)
  • the evolution of emotional communication, emotional contagion and mimicry
  • group and crowd cognition
