Training a robot in a real-life environment is more or less impossible. Computer scientist and psychologist Roy de Kleijn switched to training in a simulated, virtual one instead. ‘You do have a reality gap, but the more precisely you train the robot, the better it is in practice.’ His inspiration:…

This master’s programme combines Physics with Data Science. You will learn how physics has its own tricks to deal with big data and how techniques from machine learning and deep learning can be applied to classical and quantum data. The first focus of attention is on classical data, including data mining,…

The majority of scientists, from archaeologists through to zoologists, collect enormous volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics and computer science, we can develop algorithms for analyzing…

When you have finished your dissertation, it is time to prepare for the defence procedure.

A master's degree in Psychology at Leiden University combines theoretical knowledge with academic and professional skills, making you an attractive candidate for many employers.

In this respect, we are involved in research and development of high performance computing systems, embedded & real-time computing…

Coordination chemistry is the chemistry of metal atoms

The Institute of Security and Global Affairs (ISGA) offers courses at both bachelor’s and master’s level. There are also minors, online learning and courses for professionals.

Leiden Professor of Translational Rheumatology Hans Ulrich Scherer has one foot in the clinic, where he helps patients, and the other in the lab, where he supervises researchers. He bridges these two worlds in his hunt for autoimmune rheumatic diseases.

Data play an important role in any organization. More and more data are available about products, about production processes and about customers. At the annual LIACS Business Event on Wednesday 18 January, the central message was how to find irregularities in Big Data, and how it can help you to track…

Behavioural biologist Wouter Halfwerk has been awarded a 2-year outgoing Rubicon-grant from NWO. He will be working at the Smithsonian Tropical Research Institute with bats and frogs to understand the evolution of multimodal communication.

Nanoparticles are widely used, but their effect on the environment is unclear because they are hard to track. Leiden physicists have developed a new method to detect conducting nanoparticles. Aquiles Carattino successfully defended his PhD thesis on the subject.

Observations made with the ALMA telescope in Chile and ESA’s Rosetta mission, have detected the faint molecular fingerprint of methyl chloride in gas, a chemical commonly produced by industrial biological processes on Earth, around both an infant star and a comet.
