Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…

In February 2017 our faculty newsletter included an announcement on lecturing in China. I immediately thought I should apply.

At the faculty of Governance and Global Affairs we are proud to celebrate social entrepreneurship, which is why we decided to introduce you to an amazing project by two of our students: Kimberly Schoenmaker and Caroline Flohr. Ambitious, driven and incredibly conscious of the corporate responsibility…

Het College van Bestuur van de Universiteit Leiden heeft Dr. Johannes Magliano-Tromp benoemd tot ad interim lid van het faculteitsbestuur van de Faculteit Governance and Global Affairs met de portefeuille onderwijs.

Forum voor Democratie demonstreert telkens weer dat het geen morele ondergrens kent. Moet de rechter de democratie beschermen door partijen als Forum te verbieden? Verschillende ‘Leidse’ juristen spreken zich over deze kwestie uit in Dagblad Trouw.

Kinderen die moeilijk leren, hebben veel gemeen met kinderen die juist heel makkelijk leerstof tot zich nemen. Beide groepen kinderen doen hun best om te voldoen aan de eisen van de leerkracht en zich aan te passen aan de andere leerlingen in de klas. Omdat zij beiden een ’afwijkend leerproces’ hebben,…

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

This book explores the spiritual potential of faith, mysticism and transcendence in answer to the dangers of a mythologised state and the sacro-sanctification of (liberal) democracy and its rule of law.

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

Cardiovascular disease is the leading cause of death worldwide.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

Quantum hardware comes with a different computing paradigm and new ways to tackle applications. Much effort has to be put into understanding how to leverage this technology to give real-world advantages in areas of interest for industries such as combinatorial optimization or machine learning.

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

In summary, the collective results described in this thesis show that nanoparticulate vaccines can be delivered intradermally by coated and hollow microneedles and evoke antigen-specific immune responses.

Op 28 oktober 2021 verdedigde Hein van der Bruggen zijn proefschrift en behaalde daarmee de doctorstitel.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

This thesis is about augmented reality (AR). AR is commonly considered a technology that integrates virtual images into a user’s view of the real world.

Trigonostemon Blume is a plant genus in the family Euphorbiaceae comprising 59 species.

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

Antibiotic resistance, caused by widespread use of antibiotics, leads to bacterial infections that are difficult, if not impossible, to treat and is a major worldwide health concern.

The sequence-dependence of biomolecular interactions involving nucleic acids and proteins is essential for numerous processes inside the cell. Insights into the underlying molecular mechanisms have been obtained using various biochemical and biophysical methods on two different levels — bulk and sin…

This thesis considers multi-prover commitment schemes whose security is based on restrictions on the communication between the provers.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.
