Driven by the belief that education should be guided by evidence, Romy van Leeuwen helps to gain insight into what truly works, what doesn’t, and why. As a researcher and educational advisor at Risbo, Erasmus University Rotterdam, Romy leads and supports projects on impact evaluation of educational interventions, evaluation of bachelor and master programmes, and studies the effect of educational innovations. She develops qualitative and quantitative measurement tools, collects and analyses data, and delivers clear, tailored reports and presentations for policymakers and stakeholders. In addition to her research, she advises educators, provides teacher training, and designs visual materials to make knowledge sharing more effective. As both researcher and educational advisor, Romy strives to bridge the gap between research and (educational) practice, to eventually help create education that makes a proven difference.
