The behaviour of strongly correlated electron systems, such as high-temperature superconductors, defies explanation in the language of ordinary quantum theory. A seemingly unrelated area of physics, string theory, might give physicists a better understanding of the weird behaviour of these kinds of…

Computer scientist Bas van Stein conducted research at Tata Steel and BMW on how their production processes could be streamlined and optimised on the basis of data. As part of his research he developed some innovative products. PhD defence 20 September.

The Dick Stufkens Prijs 2010 is awarded to Dr. Niels Elders.

Their research contributes to the quest for a method to generate or store energy more efficiently. The report is published…

Theoretical physicist Carlo Beenakker has been awarded a €2m Advanced Grant by the European Research Council (ERC). He will use this to try to create the ideal building blocks for a quantum computer: ‘braided’ Majorana fermions. An ambitious project that may just lead to a major breakthrough.

Software development is probably not the first thing that comes to mind when you think of a sociologist. Three years ago, John Boy began developing his software package Textnets. Because of Corona, he was less able to concentrate on writing scientific research and also setting up the online courses…

On the 13th of December 2017 Ana Lucia Araujo came to Leiden to discuss the long history of the demand for reparations for slavery. In the basement of the Van Stockum bookstore she presented her recent book on this issue and discussed the research project with Karwan Fatah-Black.

By a stroke of luck, a team led by Dutch PhD student Martijn Oei has discovered a radio galaxy of at least 16 million lightyears long. The pair of plasma plumes is the largest structure made by a galaxy known thus far. The finding disproves some long-kept hypotheses about the growth of radio galaxie…

Good research means looking beyond disciplinary boundaries, said Professor of Molecular and Cellular Biochemistry Remus Dame in his inaugural lecture on 10 May. Processes that take place on DNA shouldn’t only be researched in a test tube but also in living cells, for instance.

For only the second time ever, astronomers have linked a neutrino to an object outside our Milky Way. These observations were made using telescopes both on Earth and in space. The researchers, including Leiden astronomer Sjoert van Velzen, were able to trace the neutrino to a black hole that is devouring…

All microscopic objects, from enzymes to paint particles, are jittering constantly, bombarded by solvent particles: this is called Brownian motion. How does this motion change when the object is flexible instead of rigid? Ruben Verweij, Pepijn Moerman and colleagues published the first measurements…

We are grief-stricken that our PhD student Maolin Zhang passed away during the early morning of January 17th 2019. He died during a terrible fire that took place at his house in Hillegom.

For centuries, astronomers have studied the universe by collecting light signals. Since 2015, the confirmation of an important prediction of Einstein allows us to explore the universe in a new way: through gravitational wave radiation. Astronomy PhD candidate Valeriya Korol proposes to use these gravitational…

It's one of the big cosmology debates: the universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey adapted an independent third measurement method, using the light warping properties of galaxies predicted by Einstein. He published…

Gerard van Westen and his group, together with pharmaceutical company Galapagos, start on developing software that invents new effective molecules. They will receive an NWO LIFT grant of 280,000 euros, of which 63,000 euros will come from Galapagos. The company will also bring its expertise in biology,…

The brain is a complex organ, and researching medicine to treat brain disorders is equally if not more complex. Elizabeth (Liesbeth) de Lange, Professor of Predictive Pharmacology, calls for a structured approach. ‘In effect, it's like playing Mastermind.’ Inaugural lecture on 22 March.

Hao Liu moved from China to Leiden to do her PhD trajectory at the Institute for Philosophy. What is it like to do a PhD so far from home?

The use of a new type of detector has generated a strong improvement in the resolution of electron microscopes. The 'low-energy electron microscope' (LEEM) can now be used for research on the thinnest possible materials. The tests with the detector represent the first result of the ESCHER project.

Beautiful microscopic specimens play the leading role in the course 'Biodiversity Plant' for first-year Biology students. Normally these are put back in storage right after the course. But not this year!

The world’s population is expected to rise to 9 billion people in 2050. At the same time, climate change urges us to dramatically reduce our use of resources. Does the transition to a circular economy offer us a way out, and if so, how? Master Honours Class’ students are looking into this issue: ‘Change…

Although smartphones and other consumer cameras are increasingly used for scientific applications like citizen science, it’s still difficult to compare and combine data from different devices. PhD student Olivier Burggraaff developed a new easy-to-use standardised method which makes it possible for…

From the late Middle Ages onwards, maritime conflict has developed hand in hand with international trade. Over time, specific institutions were established to address disputes arising from violence or mishap at sea and in coastal areas. Conflict resolution at sea has mostly been studied through the…

There are as good as no clear rules for the return of stolen art. This means that rather than in court, many cases are decided in the political arena instead. In her PhD research Evelien Campfens suggests how this could change. PhD defence on 11 November.

One of the familiar faces of our faculty is receptionist Patrick Moerland (39). He has been working for the university for 17 years and is clearly passionate about his work. You can visit him for things like lost property, difficult questions or if you can’t find your way to a lecture hall. Patrick's…

Two Leiden astronomers will receive the prestigious IAU PhD Prize. Both Jorryt Mathee and Niels Ligterink of the Leiden Observatory won a prize. Scientific director Huub Röttgering: We are proud that this year two of our PhD students receive an IAU prize for the best thesis in their field of researc…

The research group headed by Leiden chemist Marc Koper has discovered a catalyst that minimizes the production of chlorine gas during salt water electrolysis.

The Municipality of The Hague, Leiden University and CBRE Investment Management (CBRE IM) will together try to realise a University building in the former Hudson’s Bay premises at Grote Marktstraat 48-50/Spui 3. This will facilitate the growth of Campus The Hague. A cooperation agreement was signed…

Researchers from the Leiden University Medical Center (LUMC) have successfully used stem cell gene therapy to treat a baby with the severe congenital immune disorder SCID. An important milestone: it is the first time stem cell gene therapy of Dutch origin has been administered to a patient, and also…

What dose of medicine do you give a child? That depends to a large extent on how quickly their kidneys remove the drug from the blood. For ethical reasons it is impossible to measure this directly in little patients. PhD candidate Sinziana Cristea combined different types of modelling and lots of data…

Research at ELS@Leiden focuses on law and behavior in a market context.

There have been recycling bins in all of the University buildings since 2018. Waste bins were removed from staff offices at the same time. Waste such as paper, batteries and printer cartridges is now collected in separate streams. But the big question is: what happens to the different waste streams?…
