Humans & technology

Humans & technology form my drive & focus. They are both tremendously fascinating and empowering when combined allowing me to engage with meaningful challenges.

Nanda

In my research I focus on understanding human behaviour in group(s) as a part of a complex (social) system. My research can be characterised by the overall question:  ‘How does group or collective behaviour arise or change given its social and physical context?‘ More specifically, I have engaged with: ‘How is (individual) human behaviour affected by being in a crowd?’, ‘Why do some groups (cooperatively) use their resources sustainably, whereas others do not?‘, ‘What is the role of (often implicit simplistic) assumptions regarding human behaviour for science and/or management?’

To address these questions, I use computational simulations to integrate and reflect synthesised knowledge from literature, empirics and experts. Models, simulation and data analysis are my tools for gaining a deeper understanding of the mechanisms underlying such systems. More specifically, I work with agent-based modelling (ABM), simulation experiments and data analysis of large datasets. Apart from crowd modelling and social-ecological modelling, I also develop methodological tools to analyse social simulation data and combining ABM with other methods, such as behavioural experiments.

Short CV

Researcher @ Stockholm Resilience Centre, Sweden

Focus on social-ecological systems. I contribute towards deeper understanding of human (group) 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.
SES-LINKStockholm Resilience Centre |  Stockholm University

Postdoctoral researcher @ Utrecht University, The Netherlands

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.

PhD @ University of Groningen & TNO, The Netherlands

For my PhD I developed a social, cognitive model of crowd behaviour, ‘CROSS’, to study the behavioural mechanisms underlying crowd behaviour. Project: CROSS.
Faculty of Economics and Business, University of Groningen
Business Unit Human Factors, TNO Safety & Defense

Master Artificial Intelligence – Autonomous systems, The Netherlands

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.
