Flitsinterview met alumnus Kees van der Staaij: ik ben en blijf een jurist in hart en nieren

For the next couple of years, Joris van der Voet, Associate Professor and researcher at the Institute for Public Administration will be heading a research project on top-level bureaucrats and how they go about making choices and prioritizing issues. He has been awarded a Vidi grant by the Dutch Research…

Wouter Veenendaal, a political scientist at Leiden University, is an analyst for the Freedom House report. Freedom House is an American non-profit organisation dedicated to democracy, political freedom and human rights. In short, the report describes the degree of freedom and the state of democracy…

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.

Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

Fostering multi-polar perspectives that engage more connected, nuanced and pluralistic understandings of the world. Global Interactions encourages and supports research that provides significant new insights on these global processes across time and space.

This thesis investigated miniaturized mass spectrometry (MS)-based analytical methods to address challenges in analyzing biomass-restricted biological samples.

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

This book presents a new framework for regulating human-like machines designed for emotional and sexual engagement, often powered by AI.

The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

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…

On 18 May 2022, Annelien Bouland defended her thesis 'Please give me my divorce: an ethnography of Muslim women and the law in Senegal'. The doctoral research was supervised by Prof.dr. J.M. Otto, Prof.dr. M.M.A. Kaag and Dr.ir. C.I.M. Jacobs.

Relevant safety issues are associated with hazardous materials transportation, especially when transport routes cross populated areas. This article for the Journal of Loss Prevention in the Process of Industries analyses a 2015 accident with a freight train in Tilburg, comparing it to the Viareggio…

This book presents an understanding of the concept of Countering Violent Extremism from a critical terrorism studies perspective using case studies from different countries while examining the issues it raises.

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,…

We investigate emergent structures and dynamics of soft materials self-assembled from microscopic constituents.

The research group on governance of crises studies phenomena, dynamics and actors related to crisis governance. The Leiden University Crisis Research Center (CRC) is part of this Research Group.

Plants, are sessile organisms, have developed strategies to adapt to changes in their environment, in part by altering their growth and development.

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

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.

Due to the modern techniques of combinatorial chemistry and high-throughput screening, data on the biological activity of many millions of compounds is known. However, it is still very difficult to transfer this data into knowledge: if we know that compounds A and B bind to a certain protein with high…

The thesis is about how auxin and AGC kinases regulate male fertility. The main AGC kinases studied in this thesis is PDK1, PDK2 and AGC1.5, AGC1.7.

Quantum position verification (QPV) - the subject of this thesis - is a novel way to authenticate unknown nodes in a quantum network without the need to physically meet up.

The vegetative growth period for leafy vegetables like lettuce is essential for yield and quality.

Political scientist Femke Bakker (Leiden University) is going to investigate whether meditation affects political behaviour. Bakker has been awarded a PEACE Grant by the Mind & Life Institute, which enables her to conduct innovative, experimental research. The aim is an answer to the question whether…

With the Dutch general elections just around the corner, it’s not always easy when political differences exist within your circle of friends.
