Research Assistant
El-Erian Institute of Behavioural Economics and Policy
BSc (University of Amsterdam), MSc (KU Leuven)
My interests lie in several areas of behavioural science, both from a meta-scientific perspective (eg how to build better theories) and an applied perspective (eg how behavioural science can be used to promote pro-social and pro-environmental outcomes through public policy).

Professional experience
Piotr has contributed to multiple research projects in the past, including investigating the effects of financial incentives on pro-environmental behaviour at the Behavioural Economics and Engineering Group at KU Leuven, co-authoring a methodological handbook for policymakers on applying behavioural insights to enhance tax compliance at Verian Group, and mapping out the behaviours of policy officers related to their use of scientific evidence at the European Commission.
Piotr holds a BSc in Economics from the University of Amsterdam and an MSc in Psychology: Theory and Research from KU Leuven.
