Humans & technology form my drive & focus. They are both tremendously fascinating, are tremendously empowering when combined and therefore allow me to engage with meaningful challenges.
My work is characterised by a focus on understanding complex (social) systems. My research can be characterised by the question: ‘How does human behaviour arise or change given its social and physical context?‘. More specifically, I have engaged with: ‘How is (individual) human behaviour affect in crowds?’, ‘Why do some groups (cooperatively) use their resources sustainably, whereas others overexploit?‘, ‘What is the role of often implicit simplistic assumptions underlying human behaviour, for science/management?’…
To address these questions, I make use of computational simulations to integrate and reflect both knowledge and empirics. Models, simulation and data analysis are my tools to gain a deeper understanding of the mechanisms underlying these systems. More specifically, I work with agent-based modelling (ABM), simulation experiments and data analysis of large datasets. My projects have thus far focused on crowd modelling and social-ecological modelling while also exploring and implementing methodological tools for developing and analysing social simulation data.
Focus on social-ecological systems. I contribute towards deeper understanding of human behaviour in natural resource management. Case experts and data, theory and a variety of methods allow for integrating and modelling (system) behaviour from an unique angle. Projects: FIBE, agentEx and COBA.

Focus on support water policy and sustainable river management in the Netherlands. Contributed to running the serious games with water policy developers. I modelled policy decision dynamics as social uncertainty in long-term water management, based on conducted interviews. Project: adaptation pathways.

For my PhD I developed a social, cognitive model of crowd behaviour, ‘CROSS’, to study the behavioural mechanisms underlying crowd behaviour. Project: CROSS.

For my master thesis project, I developed a model of egress (people fleeing out of buildings into the streets). This project was executed in Freiburg (Germany) as a part of the RoboCup rescue simulation team ResQ-Freiburg.
