For an overview of my work, please watch this recent Donders Inclusion Seminar
For current open internship projects, see this page. Since we do mostly modelling, computer simulations and advanced data analysis (that means, bluntly said, computer programming and mathematics), some affinity and experience with math and programming would really help. For some resources, you can take a look here. If you’re motivated and willing to learn, you don’t have to be an expert of course, but especially for short internships it is better to be able to focus on the science than on learning how to program.
