In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

Having served on the Executive Board for over nine years, the last five of which as Rector Magnificus, Hester Bijl will leave Leiden University at the start of next year. In a new step in her career, she will become Rector Magnificus on the Executive Board of Delft University of Technology (TU Delft)…

Leiden University’s Rector Magnificus, Professor Hester Bijl, has been reappointed for a second term by the Board of Governors.

In this research group, headed by Bob Van de Water, cell signaling programs that underlie adverse drug reactions as well as cancer development and progression are unraveled. Adverse drug reactions involve cell injury in critical target organ cells which leads to the activation of cellular stress response…

Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

Professor Annetje Ottow will be appointed President of the Executive Board of Leiden University on 8 February 2021. She will be the first woman to be appointed to this post at Leiden University.

Alexander Kros studies supramolecular systems in a biological environment. The unifying theme between the projects in my lab is specific molecular recognition, i.e. the intermolecular interaction between complementary molecules with high affinity and selectivity. Studying, imitating and dissecting processes…
