Contribute to shaping the content and methods of future computer science education. That is what researchers hope to achieve with the Digital Transformation Research project. The Swiss National Science Foundation awarded 544,000 euros to this four-year project in December. The project will map the ideas…

Leiden University and the Beijing Institute of Technology will be collaborating in the area of computer science teaching and research. One of the first outcomes of this collaboration will be a joint four-year bachelor's programme. Willem te Beest, Vice-President of the Executive Board, and Professor…

On September 7, the Leiden Institute of Advanced Computer Science participated with a team of six students in the first edition of the Capture the Flag event 'Challenge the Cyber'. They were placed second in this national hacking competition for students.

The right student in the right place. That is what LIACS programme director Frank Takes and education coordinator Joyce Glerum are aiming to do with the ‘Wisselstroom’ project. By next year, they hope to have a standardised protocol that will make it easier for computer science students to transfer…

Design of a Linguistic System for Interstellar Communication Based on Logic

The Computer Systems, Imagery & media (CSI) research programme performs research on methods and techniques for the design, implementation and application of advanced computer systems, in particular parallel, distributed and embedded computer systems.

The fact that scientists are increasingly better able to access molecular cell and tissue data also brings with it a new challenge: how can scientists find the information they need for research among the vast amount of data available?

Programming courses are often only available in English. All the more reason for the Programming Education Research Lab (PERL) of the Leiden Institute of Advanced Computer Science (LIACS), Eindhoven University of Technology and University of Twente to translate the 'Beauty and Joy of Computing' programming…

Computer Science on place 51 in QS World Universities Ranking 2011

Natural Computing investigates algorithms and phenonema based on nature to create better and new computer science innovations.

On 13 March 2024, Carlotta Rigotti, postdoc researcher at eLaw, and Alexandre Puttick, postdoc researcher at Bern University of Applied Sciences, remotely presented the working paper 'Towards mitigating diversity bias of AI in recruitment and selection via value sensitive design' at the ACM Symposium…

Research in the natural computing cluster covers theoretical foundations, the development of new algorithms, and interdisciplinary applications of natural computing methods.

Research in this group, headed by Gerard van Westen, focusses on computational methods integrated in different parts of the drug discovery process. More specifically, topics include innovative treatments for cancer, selectivity modeling, translational research, allosteric modulation, drug resistance…

This thesis covers several aspects of quantum algorithms for near-term quantum computers and its applications to quantum chemistry and material science.

Computational linguistics uses computational methods to help answer linguistics questions across a variety of topics.

We see computer programming as an essential skill. It enables you to be self-sufficient in building tools, processing data, visualizing research output, communicating research results, etc. Moreover, it empowers you to make beautiful things.

Research in the natural computing group covers theoretical foundations, the development of new algorithms, and interdisciplinary applications of natural computing methods.

Projects within the theme ‘Computational Biology’ aim to employ mathematical or computational dynamical modelling approaches to discover novel concepts that are important for drug development.

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

The research presented in this thesis concerns one of the most important questions in software engineering of our time: how can we make sure that software is free from memory safety bugs?

The worldwide race to the quantum computer is in full swing. This computer can take on computing tasks that we can only dream of today, such as finding proteins that can be used as medicines in seconds flat. Leiden physicists have discovered how the Majorana particle can be used as a building block…

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

Beowulf clusters looking for new frontiers.

Large-scale computing infrastructure, such as supercomputers, cluster, and clouds, are already pervasive, most members of our society interact with them daily: social networks, government services, media streaming services--all systems heavily interfacing with the members of our society--are powered…
