Currently I am working as a PhD Candidate at the Netherlands Institute for the Study of Crime and Law Enforcement (NSCR) and the University of Amsterdam (UvA). I got a Bachelors’ degree in Sociology from the VU Amsterdam and a Masters’ degree in Forensic Criminology from the University of Leiden.

As of September 2021, I started my PhD research into the consequences of bystander intervention during interpersonal conflict in public space. The aim of this research is to give more insight in the costs and benefits of intervening in a conflict, not only for the bystander self, but for the conflict in general and the possible victim as well. The project will focus on topics such as bystander victimization, (de-)escalation of conflicts after intervention, and infliction of harm to a possible victim during or after an intervention. Different conflict contexts (e.g. street-fights, robberies) will be studies using CCTV footage of public space areas to see whether consequences of intervention are generalizable across different contexts. In doing this, the project will hopefully result in a well-considered advice to people about whether or not to intervene in interpersonal conflicts in public space, and, when intervening, which risks should be taken into account.

Besides the PhD project described above, I am also involved in several research projects regarding compliance with COVID-19 mitigating measures in the Netherlands. In these projects, we use CCTV footage of public space in Amsterdam to monitor compliance with certain measures (e.g. social distancing, mask-use, curfew) throughout the pandemic
