Bio: I got my PhD in Economics from the University of Lille in 2019 and currently postdoc at the Institut Catholique de Lille. After completing a master’s degree in Experimental and Applied Behavioural Sciences in Lille, I then pursued my formation in Economics with a master’s degree in “Psychology and Economics” at the University of Paris Panthéon Sorbonne. My academic research focuses on the impact of environmental contingencies on the modification of decision-making behaviors. In this regard, I design experimental protocols in order to evaluate and quantify the impact of environmental interventions on individuals’ behaviour.
Research: I’m interested in decision-making in a risky environment. My thesis focused in particular on the reference point of Prospect Theory (Kahneman and Tversky, 1979) and its adaptation https://www.researchgate.net/publication/335571296_These_Vincent_Lenglin. Currently, I am focusing on a new modeling of the reference point that takes into account the impact of the range of monetary consequences on risk-attitude (range effect).
