How and why governments engage with civil society as well as how civil society organizes itself and exerts political influence constitute the key focus of the research programme Public Governance & Civil Society. As such, this research programme offers unique expertise within the field of public administration…

Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics — or if it just looks like it does? In a groundbreaking study, physicists from Leiden, Beijing en Hangzhou found the answer to this question.

In high school, Tim van Erven read about an artificially intelligent algorithm that could solve mazes. From that moment on, he was sold: ‘There’s something magical about algorithms. With a list of fixed rules you can make them learn the most diverse things.’ This year, he won a Vidi grant, which he…

The correctness of computational systems is of great importance to our society, since it becomes ever more reliant on the benefits of computing.

This thesis mainly focuses on multimodal understanding and Visual Question Answering (VQA) via deep learning methods. For technical contributions, this thesis first focuses on improving multimodal fusion schemes via multi-stage vision-language interactions.

On 14 May 2020, Pieter Rustenburg defended his thesis 'Een algemene normtheorie toegepast op open normen in het belastingrecht'. The doctoral research was supervised by Prof. A.O. Lubbers and Prof. J.L.M. Gribnau.

SAILS (Society, Artificial Intelligence and Life Sciences) is a universitywide initiative aimed at facilitating collaboration across disciplines on the use of Artificial Intelligence (AI). It is one of Leiden University's interdisciplinary programmes.

What if you could watch a CT scan live, instead of analysing the images afterwards? If it is up to the Leiden mathematician Jan-Willem Buurlage, that will soon be a reality. He is developing methods to make the algorithms behind 3D scans faster. Quite a challenge: ‘Just like mathematicians, computers…

To easily take part in group decision-making research, Jörg Gross, Assistent Professor Social and Organisational Psychology, launched a platform that allows students at the social interaction lab. Sign up to receive invitations if you are interested in taking part in on-going scientific studies in the…

Proving a quantum computer to be quicker than a normal one is one step closer. After a breakthrough in speeding up classical algorithms, researchers Vedran Dunjko and Casper Gyurik showed that only one quantum algorithm could beat its classical counterpart. They discuss their discovery in Quanta Mag…

On 12 September 2019, Michiel Rhoen defended his thesis 'Big Data, Big Risks, Big Power Shifts: Evaluating the General Data Protection Regulation as an instrument of risk control and power redistribution in the context of big data'. The doctoral research was supervised by Prof. G.J. Zwenne and Prof.…

In healthcare, gender and sex considerations are crucial because they affect individuals' health and disease differences. Yet, most algorithms deployed in the healthcare context lack close consideration of these aspects and do not account for bias detection. In their latest paper, Eduard Fosch-Villaronga,…

It is difficult to imagine a society other than a hierarchical nation-state. This is in part because we neglect alternative forms from the past, argues archaeologist Lewis Borck in the Journal of Contemporary Archaeology.

The price of products and services plays an enormous role in society, and therefore also in the legal domain, according to Professor of Business Studies. Inaugural lecture 2 June.

Prof. Ottervanger, professor emeritus of European Law and Dutch Competition Law has analysed 36 final court judgments concerning decisions by the Netherlands Authority for Consumers & Markets (ACM) in competition cases. The report was part of the review of the ACM that was conducted by the Dutch Ministry…

From 23 to 24 February 2023, the Conference ‘The Future of the European Security Architecture: The CJEU’s decision on Passenger Name Records and beyond’ took place at the KNAW in Amsterdam.

Lack of money impacts how a person takes financial decisions: now or preferably later. Procrastination and avoidance behaviours in turn have an effect on lack of money, which can result in a sense of loss of control. These are the findings of psychologist Leon Hilbert in his PhD research, although the…

Computers are capable of making incredibly accurate predictions on the basis of machine learning. In other words, these computers can learn without intervention once they have been pre-programmed by humans. At LIACS, we explore and push the borders of what a revolutionary new generation of algorithms…

The recently promoted Hao Wang from the Leiden Institute of Advanced Computer Science teaches computer programmes how to solve real-world problems. His goal is to make the process of problem-solving more efficient. On 1 November, he obtained his doctorate with the predicate cum laude. ‘I hope to solve…

In 2009-2010, the notion of a more ‘assertive’ China emerged in Western discourse, a viewpoint that China vehemently rejects. Nevertheless, especially after Xi Jinping rose to power in 2012, it is clear that China has abandoned its long-held foreign policy doctrine of ‘keeping a low profile.’

Which brain cell does what, when Parkinson's disease arises? It won't be long before this jigsaw is solved piece by piece. Ahmed Mahfouz, computational biologist, combines bio-knowledge from Leiden with algorithms from Delft and is getting closer to finding the key.

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…

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

The Computers, Privacy and Data Protection Conference (CPDP) is the world’s leading multidisciplinary event on privacy and data protection. CPDP brings together experts to explore cutting-edge legal, regulatory, academic, and technological developments in the field, providing a premier platform for…

Yvonne Erkens and Fieke Weber, both from the Department of Labour Law and Social Security, recently organised a panel discussion on behalf of the International Labor Rights Case Law Journal (ILaRC). The discussion took place during the ISLSSL World Congress in Rome and was a huge success.

An integrated approach for the simultaneous prediction of polypharmacology and binding affinity/potency of small molecules.

The thesis is part of a bigger project, the HEPGAME (High Energy Physics Game). The main objective for HEPGAME is the utilization of AI solutions, particularly by using MCTS for simplification of HEP calculations.

NeuroSoC concentrates on multiprocessor systems on chip with in-memory neural processing units.

People come to court because of a legal dispute, and often think that the court decision will also resolve the underlying conflict. But that is not always the case. ‘Court decisions should provide a better response to the needs and the nature of citizens,’ argues professor by special appointment Rogier…

In this thesis it is posed that the central object of preference discovery is a co-creative process in which the Other can be represented by a machine. It explores efficient methods to enhance introverted intuition using extraverted intuition's communication lines.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

This monograph focuses on clustering of objects in high-dimensional data, given the restriction that the objects do not cluster on all the attributes, not even on a single subset of attributes, but often on different subsets of attributes in the data.

With tomography it is possible to reconstruct the interior of an object without destroying.

Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…
