This minor focuses on how our thoughts, emotions and behaviour are influenced by other people, and how we influence other people.

How can computers help design optimal buildings? PhD student Koen van der Blom makes algorithms that take into account all kinds of different architectural requirements, in order to reach the best compromise. And that is quite difficult: 'Algorithms do not automatically understand that a building that…

What are the essential determinants of (dis)trust? And, what are the effects of being (dis)trusted?

Our project focuses on the analysis of decision-making processes in the European Union (EU) and explores how approaches and tools to understand decision-making found in both the Natural and the Social Sciences can be linked, knowledge between these traditions exchanged and synergies utilized. To explore…

Assistant Professor Vedran Dunjko and his team received a gift from Google to support their quantum research. The research focuses on whether quantum computers can provide new ways of understanding the mysteries of high-energy physics.

We present an extensive study of methods for exactly solving stochastic constraint (optimisation) problems (SCPs) in network analysis. These problems are prevalent in science, governance and industry.

PACES is an innovative, inter-disciplinary and multi-level research project that asks, How do changes in society, individual life experiences and migration policy shape decisions to stay or to migrate over time and across countries? And how can this knowledge inform future migration policies and gov…

Analytical tools for environmental design and management in a systems perspective. The combined use of analytical tools.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

The starting point for this research project is the notion that the human brain is susceptible to all kinds of fallacies and biases that affect our perceptions and influence our reasoning outside of our conscious awareness. Indeed, most people think they are merely observing facts and that they process…

In this article, Amandine Lerusse, investigates how the order of performance information affects local politicians’ issue prioritisation decisions.

How do processes of coalition-formation influence patterns of decision-making in the European Union?

As a research project between four Jean Monnet Chairs - two located in Europe, one in Canada and one in the U.S. -- the project DEUBAL has been approved in 2010 for co-financing by the European Commission. DEUBAL aims to study changes in European decision-making due to the Lisbon Treaty, by a combination…

How do cognitive, motivational, and affective processes interact to select actions?

Nadine Raaphorst wrote an chapter for The Oxford Handbook of Administrative Justice about how two notions of fairness are studied in street-level bureaucracy literature and about the factors that influence how bureaucrats behave in this regard.

On 20 March 2019, Tim Dekkers defended his thesis 'Mobility, Control and Technology in Border Areas: Discretion and Decision-making in the Information Age'. The doctoral research was supervised by Prof. dr. J.P. van der Leun en Prof. dr. M.A.H. van der Woude.

Müller, Braun & Fraussen examine the conditions under which commissioners appear in the news and which communication strategies they pursue.

This thesis involves three topics: benchmarking discrete optimization algorithms, empirical analyses of evolutionary computation, and automatic algorithm configuration.

From predicting Alzheimer’s to the growth of organisms: psychologist Marjolein Fokkema’s algorithms can be used in many disciplines. They also provide inspiration for her songs, theatre shows and life lessons. What drives this rocking researcher?

The coronacrisis is emerging as the ultimate test for political leaders. How do national political leaders get ahead or behind ‘the curve’ of fast-changing dynamics. Martin Lodge (London School of Economics and Political Science) and Arjen Boin (Leiden University Institute of Political Science) look…

Using biologically inspired algorithms on 'edge devices', such as cameras and mobile phones, is what Svetlana Minakova's PhD research was all about. She conducted research on Convolutional Neural Networks(CNN). Making these algorithms work in different situations is a complicated task. 'Most design…

Every day we make use of devices, services and apps which contain algorithms that could be discriminating. These range from Facebook to self-driving cars, from the Tax Authorities to a rotating door.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

HEPGAME is a research project that combines the world’s fastest computer algebra system for High Energy Physics equations, FORM, with insights from artificial intelligence. The name combines High Energy Physics and Games.

On Tuesday December 19, Museum Boerhaave, the Lorentz Center and eLaw organize a public lecture on ‘Fairness and Accountability of Sociotechnical Algorithmic Systems’.

Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

As partner within the EuDEco-poject, the Centre for Law and Digital Technologies (eLaw) organized a panel titled “Filling accountability holes in algorithmic networks” as part of the 11th annual conference on Computers, Privacy and Data Protection (CPDP), January 24-26 2018 in Brussels.

The master’s specialisation Artificial Intelligence offers future-oriented topics in computer science with a focus on machine learning, optimization algorithms, and decision support techniques.

The social coalition 'Over Informatie Gesproken' (meaning ‘Speaking of Information’) recently approved eleven grant applications for research aimed at improving the information relationship between the government and the citizen. Meuwese and Çapkurt’s grant application for research into algorithmic…

In this article, Marco Cinelli, assistant professor at Leiden University College The Hague, examines proper and improper uses of Multiple Criteria Decision Analysis (MCDA) methods in energy systems analysis.

This thesis is a collection of theoretical works aiming at adjusting quantum algorithms to the hardware of quantum computers.
