Research at the Macromolecular Biochemistry group is comprised of the following research themes:

Development & Disease is one of the four research themes of the Institute of Biology Leiden.

Almost a century passed since the much-celebrated judgement in the case concerning the Factory of Chorzów was delivered. This 1928 judgement of the Permanent Court of International Justice affirmed the essential principle of ‘reparation’ in international law, claiming that ‘restitution’ is the preferred…

Young children, adolescents and students may experience learning difficulties as a result of lack of sleep. Dr Kristiaan van der Heijden investigates sleep problems and solutions for various age groups.

Plant Sciences' contribution to the Development & Disease research theme is to unravel the processes that allow plants to adapt to changing abiotic and biotic environmental conditions or stresses, with the aim to contribute to the sustainable production of food, flowers and bio-based products using…
