Peter de Vries is assistant professor at the section of Psychology of Conflict, Risk, & Safety. His past research includes automaticity in traffic mode choice, its effects on the execution of behavioural intentions in the context of light regulation, the effect of interactive feedback in household appliances on energy saving, and the effect of trust on technology use.

Recent research focuses on drone acceptance and transparency, sustainability and behaviour change, and the use of VR in police trainings to prevent ethnic profiling.
