Not everything that comes close to a black hole is swallowed by it. Black holes can also hurl material away, and that chance turns out to be considerably bigger than previously thought. Martijn Oei's accidental discovery and his subsequent research on it earned him a cum laude promotion on 12 Decemb…

With a single sample of water or soil, researches can analyse the DNA of everything that is living in that environment. During her research, PhD candidate Beilun Zhao discovered a way to analyse not only the kind of species, but also the age of the species in a water sample. The method showed its first…

How can humans and computers learn from data? To research this, scientists often use so-called Bayesian methods. Although these methods are widely used, they also have limitations and are not always easy to interpret. In her dissertation Rianne de Heide describes some of these problems and introduces…

When the PhD research has been completed and the dissertation is (nearly) finished, there are several more steps to take before you can defend it. For example, you must submit your manuscript and make preparations for the PhD defence ceremony.
