I am a postdoctoral reseracher working on the exchange and transformation of natural organic matter (NOM) at the terrestrial–aquatic interface, with a particular focus on both, dissolved organic matter (DOM) and particulate organic matter (POM). I investigate how landscapes, hydrological connectivity, and land-use regulate the sources, molecular composition, and reactivity of organic matter across spatial and temporal scales. A central component of my work is the application of NOM as an integrative tracer and monitoring proxy for biogeochemical processes in watershed systems. In this context, I work with in-situ and ex-situ water quality assessments. Methodologically, I combine optical techniques, particularly fluorescence spectroscopy, with ultrahigh-resolution mass spectrometry (FT-ICR-MS) and dual carbon isotope analyses (¹³C and ¹⁴C) to resolve sources, composition, and transformation pathways of organic molecules. My research spans agricultural, forested, and urban systems, with a specific emphasis on near-pristine high-alpine and island environments, where rapid environmental change provokes intense biogeochemical and hydrological alterations.
