This thesis advances automata learning, a key area in computer science, with applications in software verification, biological analysis, and autonomous technologies. It explores three main themes: first, it introduces a passive learning algorithm for generating compact probabilistic models from positive…

On 8 November 2021 YAL organized the successful symposium Interdisciplinary Research: Challenges and Opportunities.

Irma Johanna Mosquera Valderrama, principal investigator of the ERC GLOBTAXGOV project and Associate Professor of Tax Law has participated in the T20 task force on Trade, Investment and Tax Cooperation under the Argentinian Presidency. As a member of the task force, she has contributed to the policy…

In Leiden, light particles march into Wolfgang Löffler’s experiments one by one. His research focuses on acquiring the fundamental knowledge needed to develop quantum computers and networks.

The Leiden Faculty of Archaeology is a world renowned academic centre for the study of the past. Our archaeologists and heritage experts are involved in innovative projects all over the world.

In 2024, many of our students and staff won great prizes and secured important research grants.

How do insurance products transform intimate and personal relations? What are the consequences of the classifications that insurance companies use and how do these affect solidarity, morality and inequality?

The Joan van der Waals colloquium is an ongoing bi-weekly lecture series.

Physicists at the Leiden Institute of Physics (LION) conduct fundamental research into physical phenomena. They are inspired by curiosity and the desire to know more about the world in which we live. This research has always paved the way for new practical applications. These are something that the…

Irma Johanna Mosquera Valderrama is Full Professor Global Tax Governance, EU Holder Jean Monnet Chair EUTAXGOV at Leiden Law School (Leiden University), the Netherlands and Lead Researcher of the European Research Council (ERC) Funded Project – GLOBTAXGOV.

HOME will search for a diversity of Palaeolithic shelters during the Late Pleistocene through informed systematic surveys and excavations of archaeological sites in East-Central Europe.

The European Research Council (ERC) has awarded chemist Dr Alexander Kros a Starting Independent Researcher Grant of 1.4 million euro. He will be using the grant to study how molecules penetrate the natural barrier of a cell membrane. If his research is successful, it will in time bring about a revolution…

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

Research in the Jawerth lab focuses on using principles from soft condensed matter physics to understand important biological materials.

There is an urgent need for more physiologically relevant cell culture methods to guide compound selection in pre-clinical stages of the drug development pipeline.

Develop EPR instrumentation and methodology to investigate intrinsically disordered proteins (IDPs).

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

This thesis is a collection of experimental attempts to enhance photoluminescence of fluorescent molecules and quantum dots with single gold nanorods (GNRs) and relevant applications.
