On Saturday April 8 I held a presentation at the Open day for prospective students who are interested in the study program in Computer Science. Remarkably the Johan Bernoulli Institute at the University of Groningen (RUG) attracted over 100 participants filling the lecture hall with pupils and their parents. After the introduction I presented my personal reasons to study Computer Science, introduced what that field has to offer, provided a glimpse into several projects performed at our institution followed by a very recent biomedical hands on example lecture tailored to the audience.
