But his work helps make the digital world safer so that in future our internet banking will still be problem free, for instance. He will explain more in his inaugural…

A job thanks to COVID—something not many people can claim. But PhD candidate Vera Arntzen can. Over the past four years, she has mapped two crucial characteristics of SARS-CoV-2 infections. Thanks to her research, experts can now make well-informed decisions on matters like quarantine duration, which…

For many high school students, mathematical formulas are nothing more than abracadabra. Didactic and mathematics teacher Peter Kop wants to change this. For his PhD research, he devised a new series of lessons full of drawing assignments that learn students to assign more meaning to the formulas. Kop:…

Data science is now growing fast in many places, but scholars at Leiden University have been developing data science techniques for a long time already. Thanks to their broad-based expertise, Leiden statisticians are currently combining the achievements in statistics with the latest methods of statistical…

Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Amerindian settlement patterns and early colonial cartography in Northern Hispaniola

Each year, poppies disperse seeds that grow into a new generation of flowers. Sometimes, some of the seeds postpone their germination for a few years, for example when they’re covered by a layer of sand. Only when the sand disappears, do they start to sprout. Margriet Oomen did mathematical research…
