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.

Marjan van Dasselaar was appointed as the new ombuds officer for staff on 1 May. She will be working to create a safer working atmosphere within the University. 'There is a lot of pain felt by people who experience social insecurity. That pain always has to be taken seriously.'

Mathematics can help predict thrombosis. Mathematician Mark Alber has developed models that even aid in suggesting treatments. In the Kloosterman lecture on 27 June, he will explain how this works.

Many people at the Faculty of Humanities engage in their work with great passion and enthusiasm. It is important that employees enjoy their work and create a healthy work balance. Work Balance in Action is intended to keep the theme of ‘work balance’ on the agenda. By engaging in dialogue around this…

Lecture

In the course of 2020 the Faculty of Archaeology was bolstered by some new staff members. Due to the coronavirus situation, sadly, this went for a large part unnoticed. In a series of interviews we are catching up, giving the floor to our new colleagues. We kick off with Dr Tuna Kalayci, who joined…

X-ray and CT scanners are widely used devices in research, diagnostics and the industrial sector. And yet they are not nearly as fast and accurate as we would like. Mathé Zeegers is researching the newest technique in the field at the Centre for Mathematics and Computer Science: spectral X-ray imaging.…

Anthropologist Rodrigo Ochigame studies how AI is changing the practice of scientific research. From astrophysics to mathematics to climate science, they find that the adoption of new AI models is raising questions about what counts as reliable scientific evidence.

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’.

Two Second Prizes, two First Prizes and even a Grand Grand First Prize. Five Leiden mathematics students and their team leader have performed exceptionally well during the International Mathematics Competition for University Students 2024 in Bulgaria in early August. This even made for a Dutch recor…

On January 16, 2022, our respected and beloved colleague Prof. dr. Bas Edixhoven passed away after a short period of serious illness.

Doing your taxes, Netflixing or driving a car: more and more daily activities are supported by computer applications. It is challenging and expensive to test software thoroughly, leading to errors in most applications. PhD candidate Benjamin Lion made a mathematical framework to deal with this problem.…

Microorganisms that temporarily ‘go to sleep’ play an important role in the evolution and survival of a population. Mathematician Shubhamoy Nandan conducted research on the effect of this characteristic called ‘dormancy’ in a novel mathematical model.
