On September 30, 2022, our esteemed former colleague Gerrit Lodder passed away from the effects of Parkinson's disease. He leaves behind his wife Adry, his sons Gert-Jan and Michiel, his daughters-in-law Annerieke and Manyana and grandchildren Annelot and Gijs in sadness, but also in the knowledge that…

An interdisciplinary team of Leiden researchers has discovered that wasting syndrome, a severe byproduct of tuberculosis, is the same for all humans and animals studied. The discovery offers new opportunities to investigate the still insufficiently understood condition. The scientists also developed…

On Wednesday 12 December 2018, the department of Child Law, on the initiative of dr. Yannick van den Brink, dr. Stephanie Rap en prof. dr. Ton Liefaard), organized an expert meeting on ‘Equality, children’s rights and digital technologies’. The objective of the meeting was an in-depth exchange of ideas…

Specific fatty acid-sugar molecules allow leprosy bacteria, among others, to hide from our immune system. How exactly is not entirely clear. Hessel van Dijk, who received his PhD on 13 October, replicated the molecules, helping to solve a piece of the puzzle. Van Dijk's dissertation is titled: Synthesis…

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.'

PhD candidate Marc Baggelaar of the Leiden Institute of Chemistry (LIC) graduated cum laude on Thursday 6 April. His thesis on the endocannabinoid system in the brain is very comprehensive and of high quality, according to the jury. ‘A very talented young scientist, that definitely belongs to the top…
