As a non-invasive genetic method, eDNA based approaches have become an important component of ecologists' and environmental managers' toolkits for biomonitoring in conservation and an increasingly important source of ecological knowledge.

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

The new institute manager of the IBL studied biology for six months, but went in a completely different direction: development cooperation and the financial sector. Three decades later, Resi Janssen is making a radical career switch. Or isn’t she? 'In ten years’ time I want IBL to be in a new, sustainable…

Luc Verheij, Professor of Constitutional and Administrative Law (Kircheiner chair) at Leiden Law School has been appointed as a member of the 'Raad van State', the Dutch Council of State. Verheij was already a State Councillor at the Advisory Division since 2011. He will continue to fulfill this role…

The project GRADIENTS investigates what it meant to be European in colonial Africa where identification as European often did not depend on skin colour and was understood on a spectrum with many gradients.

How can zebrafish research help to understand and fight human cancer?

The chain that supplies patients with new medicines consists of various complex links: from fundamental research to clinical tests and production. This entire chain is represented in Leiden. Leiden University, the Leiden University Medical Center (LUMC), and the companies on the Leiden Bio Science Park…

Heart failure is a major health care problem with high mortality.

On Friday 23 November 2018 Professor W. (Willemien) den Ouden and Professor J.E. (Jacobine) van den Brink acted as keynote speakers at a conference entitled Private Enforcement of European Competition and State Aid Law: Current challenges and the way forward.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

An attractive feature of the MSc Chemistry programme at Leiden University is the great flexibility of the study programme, allowing students to put together a tailor-made programme following their personal interests. Within the limits set by the programme, students can make their own choices and adjust…

Some examples of AI-research done at Leiden.

Yeast, alpacas, and antibodies. They may seem unrelated, but within the project of the Leiden iGEM students, they come together perfectly. For the international synthetic biology competition iGEM, the team is working on an innovative method to produce nanobodies—a special form of antibodies—using brewer’s…

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.

Transparency is seen as an important value for democratic government policy. Does that mean that we should do away with state secrets, such as confidential information involving intelligence agencies and political deals made behind closed doors? Political philosopher and ERC grant recipient Dorota Mokrosinska…

On Thursday 12 October 2017 Janneke Wesseling will give a lecture as part of the Studium Generale Programme at Eindhoven University of Technology (TU/e).

Our research is aimed at a smoother and speedier transition from preclinical research to pharmacological interventions, and the delivery of drugs in the human body by use of small molecules and biologics.

The Leiden Institute of Chemistry organises and participates in several programmes for high school students and teachers.

How do you fit two meters of DNA in a tiny compartment and at the same time are able to access the right parts of it at the right times?

The master's specialisation Bioinformatics at Leiden University focuses on research, development and application of computational tools and approaches for expanding the use of biological, medical, behavioral and health data.

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

Serhan Afacan defended his thesis on 23 June 2015

The US travel restrictions are deeply regrettable. Support will be offered to students and staff who are affected.

Increased molecular knowledge of the mechanisms of processes in the cell can lead to better medicines or new methods for combating diseases. Our MSc students in Life Science and Technology (LST) specifically learn to understand the molecular and structural chemical and biological aspects of disease-related…

From 1 October onwards, Dennis Claessen and Marcel Schaaf will be the new directors of education of Biology. They will replace Han de Winde. Schaaf will be responsible for the bachelor, while Claessen will mainly focus on the master tracks of Biology. We gave students and the education office the change…

Leiden University regularly confers honorary doctorates, and presents awards and prizes.

The debate on tax evasion by multinationals is in full swing in many Member States. Last week it was announced that the European Commission has started an investigation into possible illegal State aid from the Netherlands to Nike. It is likely that dozens of other companies are getting away with it.

Alexander Kros studies supramolecular systems in a biological environment. The unifying theme between the projects in my lab is specific molecular recognition, i.e. the intermolecular interaction between complementary molecules with high affinity and selectivity. Studying, imitating and dissecting processes…

Sander van Kasteren only noticed some small, subtle changes since he was appointed professor on 1 May. Still, he has to get used to the idea, even though he had been working towards the professorship for a few years. ‘I don't quite see myself as a professor yet.'

Mashaghi lab conducts research at the interface of physics, engineering and biomedicine. We develop and use theoretical and experimental approaches to address basic and applied research problems.
