LLP Essentials makes up the core component of the Leiden Leadership Programme and consists of 4 EC.

Optical cavities are useful tools to enhance the interaction between light and matter, which is important to make good quantum emitters. However, it turns out that the cavities themselves (without any quantum emitters) are already interesting objects to study.

The lecture series 'Humanity in the Automated State' examines how AI and automated systems are transforming government and public administration and what it means to be human within these digitised institutions.

Our lectures are open to anyone with an interest Find your inspiration for interdisciplinary research

Within our Faculty you may find scientists and students from the highest tier. On this page you can explore the different prizes and grants we have accumulated over the years. Ranging from sports achievements to Spinoza prizes. From ERC grants to royal distinctions. Each and every one an achievement…

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.

We interviewed lecturers and students about their experiences with courses on sustainability.

To what extent can contingent, formative feedback in lectures, facilitated by web-based ICT, increase students’ self-efficacy and (academic, behavioral, and cognitive) engagement? And how are self-efficacy and engagement influencing students’ performance and course evaluations?

Today, everybody and everything produces data. People produce large amounts of data in social networks and in commercial transactions. Medical, corporate, and government databases continue to grow. Sensors continue to get cheaper and are increasingly connected, creating an Internet of Things, and generating…

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

The research groups within the biological, soft and complex systems research area study the physics of a broad range of biological and soft materials. This spans both experimental and theoretical research.

Of the 111 Spinoza Prizes that have been awarded since 1995, 28 have gone to researchers from Leiden University.

This inaugural lecture discusses the question: How to cooperate in the digital era?

Molecular materials have been a subject of interest in fundamental research and applications for decades, and have been studied as bulk crystals, (thin) films and as individual molecules, due to the large variety in their properties. This dissertation explores pentacene crystals near the two-dimensional…

Can we make quantum devices from quantum surprises? And can we explore and build life from the nanoscale up?

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…

This dissertation revolves around the design and implementation of novel instrumentation and related measurement techniques, at the single molecule level, for use in biophysical research. Chapter 1 presents an introduction to the field of fluorescence-based single molecule measurements. In particular,…

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

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.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

By comparing individual health data with population data, doctors can provide personalized health advice and patients can learn from each other's experiences. Wessel Kraaij, professor of Applied Data Analytics shows how personal data can have predictive value.

On May 27th 2016 an inaugural lecture was held by prof. dr. Sandra Groeneveld entitled: ‘Het belang van bureaucratie. Omgaan met ambivalentie in publiek management’.

Where European integration has long been understood as a peace project, Joris Larik argued in his Havel-Cleveringa Lecture that recent developments point to an accelerated shift towards a European Union that places its interests, security and geopolitical position more centrally.

The dissertation by Max Kusters (PhD at ICLON) examined ‘teacher agency’: the capacity of university lecturers to actively and purposefully influence their teaching practices and work conditions.

Bacteria are everywhere. They are the most abundant organisms on earth and impact all aspects of our lives. They determine our health and shape our environment. Ariane Briegel, professor of Ultrastructural Biology, freezes bacteria super fast to gain a true-to-nature image of the internal and external…

Lecture

What is and should be the role of universities in supporting business? How can business benefit more of relationships with science? And what is the role of policy makers in supporting a productive relationship between science and business? Professor Simcha Jong Kon Chin examines the interactions between…

Tuberculosis bacteria and other intracellular pathogens use cells of our immune system as Trojan horses to spread into tissues. Annemarie Meijer, professor of immunobiology, explains how research into innate defence mechanisms using zebrafish inspires novel strategies for infectious disease treatmen…
