In terms of content, my topic 'Measurement across the sciences' worked very well, and I learned and discovered things that I could not have thought of in advance. Engaging with colleagues at the IAS was always useful and fun. Over the course of my fellowship I organized two events. One was a documentary viewing of the movie 'Als de nacht maar niet valt' (If only night wouldn't fall) about measurement in the context of mental disorders, with a discussion afterwards with the filmmaker and scientists. The other event was a two-day international workshop entitled 'Exploring the interaction between conceptualization and measurement across the sciences' for early-career researchers located in Europe. As a result of this workshop, a network of researchers working on measurement in various scientific disciplines has been established.

Apart from these two events and the resulting network, the following activities arose from my fellowship:

• An interdisciplinary reading club on measurement;
• Participating in a workshop on measurement in the human sciences in Cambridge and contributing a paper to the associated special issue;
• Several talks at research groups across UvA;
• A plan for a book containing interviews with scientists from various disciplines about fundamental issues in measurement in their field;
• Participation in various workshops, events and collaborations at the IAS, including UMH, AI, M&D and the Psychological methods department.

I am delighted to be part of the IAS community and I look forward to staying connected through the 'Measurement' theme that I have established and will continue as part of the broader 'Foundations and methods' theme of the IAS.
