Ultrafast linear and non-linear spectroscopy : from biological light-receptors to artificial light-harvesting systems
… and photochemistry of biological photoreceptors and address the light-induced excited-state processes in a particular molecular device that serves as a - structurally - very simple light-harvesting antenna and potentially as a catalysis-switch for the production of hydrogen in solution. …

Light-sensing in bacteria
Light reception plays an important role in regulating lifestyle changes in bacteria. My research focused on a number of different light-sensing systems in different bacteria: PpaA in Rhodobacter sphaeroides, PixD-PixE in Synechocystis sp. PCC, and the known light-receptors in Rhodospirillum …

Quantum Mechanical/molecular Mechanical Studies of F(1)-Atpase and a Plant Photoreceptor
The plant blue-light receptors of the phot family mediate plant phototropism and contain two light, oxygen, and voltage (LOV) sensitive domains as photoactive elements. We have performed QM/MM simulations of the photocycle of a complete Phot-LOV1 domain from C. reinhardtii. We have investigated the …

Engineering a cyanobacteriochrome two-component system into a synthetic, light-controlled gene expression system for plants
… way. Our lab has reengineered the CcaS/R light receptor two-component system from cyanobacterium Synechocystis sp. PCC 6803 into a plant-compatible synthetic light-controlled gene expression system called Highlighter. This system was initially deployed in transiently transformed *Nicotiana …

Structure-function analysis of phototropin receptor kinases
… in addition to being a vital energy source light can also serve as an environmental indicator. In order to maximise light perception, plants have evolved a suite of photosensors with differing sensitivities, which in combination provide detailed information regarding light availability and …

The Function and Regulation of Photobodies in Phytochrome Signaling
<p>Light is a critical environmental signal that regulates every phase of the plant life cycle, from germination to floral initiation. Of the many light receptors in the model plant <italic>Arabidopsis thaliana</italic>, the red- and far-red light-sensing phytochromes (phys) are arguably the best …
