Ultrafast spectroscopy, Photochemistry and Biophysics Research Group

Photochemical reactions drive some of the most essential biological processes, such as photosynthesis and photoreception. Additionally, they play a growing role in enhancing our quality of life through advancements in biotechnology, healthcare, green energy, and chemistry. Our research focuses on studying the molecular mechanisms of photoinduced processes, including light-triggered molecular transformation dynamics, photoreception, photoprotection and light harvesting. These processes commence on the ultrafast timescale, and often proceed via a series of slower intermediate steps. To investigate the associated reaction dynamics, we employ a range of time-resolved optical spectroscopy techniques, including UV/vis/mid-IR transient absorption and fluorescence spectroscopies. To unravel the complex kinetics of these reactions and processes, we implement state-of-the-art spectroscopic set-ups and develop tools for in-depth analysis of the experimental data (OPTIMUS). Ultimately, our aim is to develop a comprehensive understanding of how molecular systems transform light energy into function and based on this knowledge, to derive design principles for optimized photoactive constructs for application in bio- and nanotechnology.
