What has been your career path so far?
“I studied chemistry in Utrecht, and from my third year onwards I really focused on physical chemistry, mathematics, and physics. In that year I also started my minor project in colloid science, which turned into my main research project. I think my passion for colloids started there and then. After my PhD in Utrecht, during which I studied the structure and dynamics of colloidal hard spheres, I was a Humboldt Fellow in Stuttgart. Then, in 2007, I started my own research group in Oxford, UK. Being an independent group leader, I certainly learned a lot and I enjoyed my time in Oxford and the UK very much.”
What makes it fun for you to go to the lab every day?
“I have always had an interest in addressing fundamental and longstanding problems. Also, I really like working with my group members who are creating and uncovering cool things. This process is fantastic.”
How did you end up at Radboud University?
“We have been keeping an eye out for a place closer to our family, and some years ago I already experienced a positive atmosphere in Nijmegen when discussing with some now-IMM colleagues. So, when this position became vacant, I enquired and eventually decided to apply, which resulted in me getting the opportunity to continue my work here in Nijmegen. To this end, we moved our whole lab, including 4 group members - PhDs and technicians - from Oxford to Nijmegen.”
What is your research focus?
“We study soft condensed matter systems with a particular focus on colloidal suspensions, which we use to study a wide range of fundamental condensed matter science questions. A few examples include: ‘How does a crystal melt into liquid?’, ‘How do defects in crystals move?’ and ‘How does friction emerge at the particle scale?' "
What exactly are colloidal suspensions?
“In colloidal suspensions, particles with dimensions ranging from a few nanometres to a few micrometres are suspended in a solvent. Daily life examples include mud, milk or blood. These colloidal particles can be used as a versatile model system for atoms and molecules, as their phase behaviour is analogous. However, the typical colloidal length (micrometre) and time (second) scales make it possible to directly ‘look’ at colloidal particles in real space and time with relatively simple optical microscopes. Also, we use chemistry to ‘cook’ these particles and lasers (optical tweezers) to manipulate them.”
