I have been a PhD student at PS-ISRR since September 2024 after completing my master's in Advanced Spectroscopy in Chemistry EMJMD. Since my master's thesis, I have been especially driven by the photophysics and photochemistry of transition metal complexes in aqueous media, particularly by the fundamental aspects that give these materials their well-known complexity and versatility. To do that, I use a series of UV-visible-pump, X-ray probe techniques. The X-rays are essential in this regard, as they give local information for each atom inside the molecule with the increment of probing the electronic structure of their moieties, while the UV-visible light is responsible for inducing the photochemical chances in these complexes. With the combination of these two and a strong simulation backbone, we interpret the experimental spectrum to get information on how these atoms "dance" in water across very short time scales.
