After a week of shadowing for her master's degree in Public Sector Management, it has become very clear to student Loes what a manager's day looks like. 'He was putting out fires all day.'

'The way we consume information has changed dramatically over the past fifteen years. You're no longer just a receiver; you participate, create, and spread information. So why not use that to improve society?'

Jasper Knoester is the dean of the Faculty of Science. How is he doing, what exactly does he do and what does his day look like? In each newsletter, Jasper gives an insight into his life.

Physicist Milan Allan will build an instrument that will bring superconductivity research further. He has been awarded an ERC Consolidator Grant of 2 million euros over the next five years. With his PairNoise programme he aims to detect paired electrons as they occur just above the temperature at which…

Studying and being an entrepreneur at the same time? Stan (21), a master's student in Crisis and Security Management, is doing it. With the knowledge gained from his master's, he developed a game about cybersecurity: HackX. Through HackX, he wants to make others aware of dangers online.

On 28 and 29 April 2022, the fourth annual PhD Workshop on European and International Insolvency Law took place, organised by the Foundation Bob Wessels Insolvency Law Collection (BWILC). A shared first prize was awarded to Gert-Jan Boon (Leiden University) and Theodora Kostoula (European University…

They explain how they use Shuttel and…

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…

Life returned to something resembling normal after Covid but other crises soon took its place. These great challenges are also being felt at the University and our researchers are working on solutions. The nitrogen crisis, problems with young people’s services and an increasingly urgent climate crisis:…

How can you increase the effectiveness of inspectors using responsible artificial intelligence (AI)? This is the question the Innovation Center for Artificial Intelligence (ICAI) Lab AI4Oversight is tackling. By developing algorithms and methods, they try to provide optimal support for, for example,…

Even embryos can become embroiled in an evolutionary arms race with another species. Leiden biologists demonstrate this with larvae of the rosy bitterling that parasitize the gills of freshwater mussels. They published their research on February 19 in PNAS.

Generations of Leiden students and academics have done archaeological research into the early medieval history of Oegstgeest. This makes this old settlement one of the best-documented sites from that era. In a new book Leiden researchers take stock.

Four researchers from Leiden University have been awarded NWO Open Competition grants in the Science domain. This is for research into subjects such as immune cells in tumours, antibiotic resistance and magnetic semiconductors.
