Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

On 22 November, Leiden scientist Jan Vonk received an ERC starting grant for his research on the building blocks of mathematics. This grant is not his first this year: in fact, this July Vonk also received a Vidi from NWO. Four questions to the scientist who got two grants this year.

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

In analogy to mathematical proofs, the goal of a proof system is for a prover to convince a verifier of the correctness of a claim.

Microneedle-based vaccination has several advantages over vaccination by using conventional hypodermic needles.

The Mathematical Institute is one of the eight institutes of the Faculty of Science. The institute operates as a single unit defined by the activities of its members.

When you apply for admission, you’ll be asked to submit several documents.

As of 1 October, David Holmes has been appointed full professor of Pure Mathematics at the Mathematical Institute (MI). His work lies at the intersection of algebra, geometry and number theory.

On January 5, Rosa Winter will obtain her doctorate in arithmetic geometry. She researched solutions of equations that define so-called ‘del Pezzo surfaces’. ‘I like geometry because I can imagine and draw the shapes and objects,’ says Winter. ‘That makes abstract mathematics feel more tangible.’

The Mathematical Institute offers a bachelor programme in Mathematics and master programmes in Mathematics and in Statistical Science. The institute also teaches many mathematics and statistics courses in other academic programmes of the university. About 65 PhD students work on a thesis in a small…

MRFM combines the principles of magnetic resonance and atomic force microscopy.

Coordination chemistry is the chemistry of metal atoms

Your time at Leiden is about more than just studying. Some of your best experiences will stem from being a part of our lively and diverse student community, as well as from life in the beautiful city of Leiden.

Welcome to the Leiden Science community! Throughout the year, our faculty hosts a range of events designed to bring together students and staff. From interesting lectures to lively gatherings and ceremonial milestones, there’s always something happening for you. Explore the upcoming events and make…

During the award ceremony of the Christiaan Huygens Prize on 16 October, mathematician Rosa Schwarz received an honourable mention. Schwarz, former PhD candidate of the Mathematical Institute, received the mention for her dissertation ‘Logarithmic approach to the double ramification cycle’.

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

The Mathematical Institute has a rather liberal management structure. Tasks and responsibilities are distributed among the staff. Important decisions are taken by consensus. Various organisational divisions are featured below.

Ronald Cramer has been awarded an ERC Advanced Grant for his proposal 'Algebraic Methods for Stronger Crypto'. He will receive 2.5 million euro for research in the upcoming five years.

Vietnamese mathematician Dung is the first to complete his dissertation within the Erasmus Mundus Algant PhD-programme, under the supervision of Prof.dr.Hendrik Lenstra. The defence of his thesis ‘Profinite groups with a rational probabilistic zeta function’ will take place on 14 May 2013 on 13h45 in…

The research of the Mathematical Institute is driven by the curiosity of its members and has many internal and external connections. It can be characterised as fundamental but with an open attitude towards applications.

On 4 April 2018 the Stieltjes prize 2016 was awarded to Djordjo Milovic for his PhD thesis 'On the 16-rank of class groups of quadratic number fields'.

As from 20 July, six people are being interviewed for over three hours for the Dutch television show ‘Zomergasten’ at the VPRO.

PhD candidate Ludwig Hoffmann will spend two years at Harvard University in the US thanks to a Rubicon grant he won on April 11. Using theoretical models he studies biological tissues, for example during morphogenesis. This is the process that causes tissue or organisms to develop their shape. ‘This…

The discovery of a new Mersenne prime was discussed on national TV by Hendrik Lenstra and Bas Jansen, who defended his thesis on Mersenne Primes in december, and by Ionica Smeets.

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

Your tuition fee depends on a number of factors, such as your nationality and your previous Dutch higher-education qualifications.

Micro-credentials make education for professionals even more accessible. If you follow a module of 3 to 30 EC (European Credits), you receive a micro credential after completing the education program. This digital certificate is recognized by 22 universities of applied sciences and 12 universities.

Two Leiden researchers have been awarded a Consolidator Grant by the European Research Council (ERC). This grant of up to 2 million euros will enable them to continue and develop their research.
