Photosynthesis is driven by light, yet too much light is harmful for the photosynthetic organisms. In our group we investigate how plants and cyanobacteria cope with differences in light quantity and quality. A multi-disciplinary approach combining biochemistry, spectroscopy and microscopy is used to unveil the beautiful solutions photosynthetic organisms evolved to survive on our dangerous planet.
Main experimental techniques
Confocal microscopy and Fluorescence Lifetime Imaging (FLIM)
Ultrafast picosecond fluorescence
Isolation and biochemical characterisation of photosynthetic complexes
3D organisation of the photosynthetic thylakoid membrane
Light acclimation of the photosynthetic machinery of plants
State transitions resolved in space and time
The spatial heterogeneity of the cyanobacterial thylakoid membrane
Light harvesting in photosystem I and photosystem II
Ahmad Bhatti started his PhD in 2017. He investigates how cyanobacteria cope with different light conditions. To this end he combines advanced ultrafast fluorescence spectroscopy and microscopy to spatially and spectrally resolve the acclimation processes. His work is published in BBA bioenergetics https://www.sciencedirect.com/science/article/pii/S0005272820301055 and Plant Physiology https://academic.oup.com/plphys/advance-article/doi/10.1093/plphys/kiab063/6134091.
Christo Schiphort started his postdoc in 2020. He uses molecular biology, biochemistry, ultrafast fluorescence spectroscopy and confocal microscopy to investigate the functional plasticity of the thylakoid membrane.
Peter Bos started his PhD in 2021. He uses a combination of biochemical and microscopic techniques to explore the organisation and functional plasticity of the thylakoid membrane from plants and cyanobacteria.
