About me

Martina Testori is a computational social scientist studying how different means can be used to sustain cooperative and sustainable behaviors.

Martina looks at how information, including gossip, and reputation impacts cooperation in groups and communities. She is also interested in how different interventions can promote more sustainable behaviours and the achievement of sustainable development. Martina uses experimental methods and agent-based modelling to investigate cooperative and socially sustainable dynamics at the individual and collective level.

Martina is currently a Postdoctoral Fellow at the Vrije Universiteit Amsterdam. She completed her PhD in Applied Mathematics at the University of Southampton in 2020.
