Research Interest & Short CV

  • Environmental psychology
  • Mental models & Decision-making
  • Environmental literacy

Co-PI in the interdisciplinary  MultiTip project within which she investigates mental models on the Nile perch fishery among Lake Victoria stakeholders. For this project, she has developed M-Tool, a software for capturing mental models. This is the first tool that offers a standardized approach that does not require participants literacy for eliciting mental models.

She is part of a select team that is trained at the Postdoc Academy for Transformational Leadership, funded by the Robert-Bosch-Stiftung. The 2-year program trains the next generation of leaders in sustainability and transformation research in Europe.
