In my research, I translate fundamental polymer physics models to technological applications. My students and I study the properties of functional polymer surfaces. These coatings can be employed in advanced sensor platforms and in separation technologies that enable the transition to a circular economy.



Research profiles

I am the program director of Applied Physics (AP). In this role, it is my aim to ensure that AP stays the top programme is currently is. Within AP we train high-quality professionals within a strong community of students, staff and teachers, in which we facilitate that everyone can bring out the best out of themselves.
