As a new vision on food production, the feasibility study on LED light to grow crops with the biological- and chemical evaluation of final products.

In late May 2019, the Food citizens? team traveled to Poland for a project meeting and team outing. This was made possible by the European Research Council’s support and facilitated networks and knowledge-generation.

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

Intelligence of the crowd, or in other words, intelligence of a large, random collective, exists mostly in social media platforms such as twitter. The collective does not comprise (at least not necessarily) experts on crises, just regular people mostly. Nevertheless, there is valuable intelligence to…

A tidal basin is an inland sea which is almost entirely enclosed by land and connected to the open sea by a tidal inlet. Through the tidal inlets interaction takes place between the tidal basin and the open sea.

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

We are aiming to develop novel technologies to allow better sample preparation or coupling of analytical methods to (i) analyse ultra small samples, (ii) to analyse more metabolites in a quantitative manner and/or (iii) increase the sample throughput.

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.

On this page you will find resources developed by the project team, such as bibliographies, reading lists, template case-studies as well as the team's training and seminar activities.

International trade plays a critical role in global food security, with global consumption having highly localized environmental impacts.

Planet formation is a surprisingly homogeneous process that does not take place gradually from inside out, but that occurs everywhere at the same time in a proto-planetary disc, as Dave Lommen has discovered. He will obtain his doctorate this week based on his research into the dust around young stars…

Molecular complexes can be used as electrocatalysts for oxygen reduction, water oxidation, and/or hydrogen peroxide production.

We are developing biology-driven platforms to measure metabolites based on liquid chromatography-mass spectrometry (LC-MS), gas chromatography-MS (GC-MS), and capillary electrophoresis-MS (CE-MS).

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

The number of lions in Kenya is decreasing alarmingly, due partly to the encroaching cities and the development of the countryside. Together with local scientists and inhabitants, Leiden biologists are studying how this decline can be halted. ‘Lions are cleverer than we thought.’

On the Indonesian island of Siberut, the term 'hungry' does not just refer to the lack of food, but above all the absence of social contacts to use a meal.

A political science perspective on our project’s comparative ethnography. I truly enjoyed the one-day conference on February 4th where the research results have been shared with the members of the Advisory Board. The work conducted so far is impressive, and the case studies are very useful in understanding…

This thesis describes the synthesis and biological evaluation of TLR2/6, TLR4, TLR7/8 and TLR9 ligands, of which the activity can be conditionally controlled.

FAIRDOM consortium is an open initiative of various partners including funding programmes, large-consortia, institutes, small groups as well as individuals.

Advisory Board member Francesca Forno shares insights about the Food Citizens? project.

Are you a great photographer? Or not at all, but you do have a brilliant photo that captures the relationship between food and people? Join the photo contest ‘Food & Society’ of our Faculty and send in your best photo before 3 April 2018!

We asked our Winter School students to evaluate the effect and significance of this learning experience on their current research trajectories and future plans. Here are some reflections.

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

New drugs for use as tuberculosis (TB) treatment are needed due to the constrains of classical antibiotics against TB and the rise of antibiotic-resistant strains, making TB a harder and harder disease to treat.

Rebecca Tompkins defended her thesis on 21 March 2019

This is a study of Plateau Shimakonde, a sub-dialect of the Makonde language which is spoken on the Makonde Plateau in northern Mozambique.

The aim of the project is the development of polypept(o)ide-based delivery systems to use siRNA as systemic applicated therapeutic agent against e.g. solid tumors

We investigate bacteria and fungi to understand their malicious or beneficial impact on food crops and their pathogenic or antibiotic role in human health.

Practically the whole world came together on International Cultural Night on 29 November. International students got together on this night organised by Meeting Point for Refugee Students and showed their culture through dance, poetry, film and of course food. A great source of inspiration for fascinating…

You can ask virtual assistant Siri about the weather, but you can’t have a real conversation with it yet. You can’t refer to anything that’s been said before, or ask the system why it says what it says. Stephan Raaijmakers, Professor by Special Appointment from TNO, hopes to change this.

The environment also benefits when people follow national nutritional guidelines, Paul Behrens demonstrated in research published in PNAS. The publication attracted media attention both at home and internationally.

Previous research has found important inter-individual differences in the pharmacokinetics (PK) of morphine in special populations such as children, the morbidly obese or the critically ill.

The Winter School of the Food Citizens? project has been a success! Running from Monday 24th January to Friday 4th February 2022, with this milestone we handed down the project’s methodological toolkit as a team. Nine participants attended in Leiden, coming from Belgium, Ghana, Italy, Lithuania, the…

National Meat Free Week (Nationale Week Zonder Vlees, 7–13 March) is an initiative to reduce meat consumption. Assistant professor Paul Behrens is studying what impact a change in our food consumption would have on the world. What, according to him, are the main reasons to switch to a (mainly) plant-based…

The flavour of foodstuffs can be predicted by measuring the dynamic of their chemical components. Researchers, including Thomas Hankemeijer, will receive a grant from the Netherlands Organisation for Scientific Research (NWO) for research in this area. They will work with DSM and Unilever.

This thesis consists of two main parts. The first part (Chapters 2 and 3) deals with a class of Markov process called Quasi-Skipfree (QSF) processes.

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

My ERC Starting Grant, funded with €1.5 million for 5 years as part of the Horizon 2020 research and innovation program, is focused on building the early warning system WARN-D to reliably forecast depression in young adults before it occurs. Why depression, and why prediction?
