BREAKING NEWS The Netherlands Organization for Scientific Research has awarded me a VICI fellowship for the research project 'Shedding light on the optogenetics toolbox'. I will use sophisticated laser techniques to determine the light activation mechanisms of photosensory proteins that have great potential for optogenetic application. The award (1.5 million Euro) will primarily be spent to appoint young researchers

My research involves the physico-chemical mechanisms of reception, storage and processing of photic energy and information in biology. To this end, advanced time-resolved spectroscopic methods are employed, such as ultrafast transient absorption, time-resolved IR spectroscopy, 2-dimensional IR spectroscopy, step-scan and rapid-scan FTIR and ultrafast Raman spectroscopy. Ongoing research projects are focused on light-driven signal transduction mediated by novel photoreceptors and the mechanisms of regulated light harvesting in natural and artificial photosynthesis.
