Marijn is Assistant Professor at the International Institute of Social Studies (ISS), Erasmus University Rotterdam. Her research focuses on collaborative development policy processes to address poverty, climate change, and food insecurity. She likes to undertake multidisciplinary and transdisciplinary research, and uses action-oriented research approaches where possible.

Marijn's interests can be classified along three lines.

The first line focuses on strategies by different actors - public, private, civil society - to influence agriculture and climate change policies at various levels.

The second line revolves around private-sector engagement in development, with a focus on inclusive business initiatives and value chain partnerships, and the processes and dynamics influencing inclusive development objectives and results.

The third research line is about monitoring and evaluation (M&E), with a particular focus on complex multi-actor collaborations for development, challenges around assessing systems changes and monitoring and evaluating adaptive approaches.
