About me

Julien has a BSc. in Economics from Ecole Normale Superieure Paris-Saclay and a BSc. in applied Mathematics from University Paris XI. In 2018, he received an MSc. in Economics from University of Paris-Saclay, where he specialised in decision theory and econometrics. From October 2018 to April 2019, Julien worked as a research assistant in the experimental economic laboratory of Paris before joining the MPhil/PhD programme in Environmental Economics at LSE.

Julien’s PhD work focuses on designing and assessing behavioural policies to foster pro-environmental behaviours. Julien is particularly interested in the factors affecting the effectiveness of these behavioural interventions and their side effects on decisions they were not initially targeting.
