An overview of the research at the Biologics Formulation group

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars (exoplanets). They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

How does the evolution of the archaeological landscape at Son Sard reveal rural settlement patterns on Mallorca, serving as a pars pro toto for Balearic rural archaeology?

Learning about circadian rhythms can help students to improve their sleep and overall well-being

The master’s specialisation Research in Physics, Quantum Matter and Optics at Leiden University offers a thorough experience on the front line of physics research with a practical training of communicative and computer skills. The programme focuses on Condensed Matter problems, such as Molecular Electronics,…

The central aims of this project are to establish the shapes of the various urban hierarchies existing in the provinces of the Roman Empire and (especially) to use the quantitative properties of these hierarchies to shed new light on levels of economic integration.

How many men and women die per year at the hands of others? What are the motives behind these killings? Are there as many homicides today as years ago? How can we explain the rise and fall of homicides over time? And: What is the influence of (early) childhood and adolescence on the likelihood to commit…

Big Science, commonly defined as conventional science made big in three dimensions, namely organizations, machines, and politics, brings a plethora of different stakeholders together, often for a long period of time. This includes policymakers, scientists, (scientific) managers as well as local “host”…

PURPOSE: To determine the effect of elasticity on the skin permeation of ketoprofen from surfactant-based vesicular formulations and elastic liposomes.

A growing amount of literature is being devoted to interrogating gendered dynamics in both violent extremism and terrorism, contributing to the integration of international and feminist security. This includes how such dynamics can shape differences in the motivations and participation of women and…

Politicians' statements often involve emotions, shaping public perceptions. This study highlights the role of emotions in EU foreign policy.

IBL researchers use the facility to study a wide range of wildtype and transgenic plants, including Arabidopsis, tomato, barley, rice, lettuce, radish, ornamentals, and various trees. Research also involves the interaction between plants and various microorganisms and insects, providing valuable insights…

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

On 22 February, Elody Hutten defended the thesis 'Tax Professionals Under Societal Pressure: A Dutch Case Study on Responses to BEPS'. The doctoral research was supervised by Henk Vording en Jan Vleggeert.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

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.
