Aquatic biogeochemistry has been the focus of my research through my training; I find intriguing and exciting the interpretation of chemical elements’ ecological roles in ecosystems. During these years of studying phosphorus recycling in aquatic ecosystems, I became curious about other essential components in the chemical environment, such as organic matter. Through modern quantifying tools, such as fluorescence spectroscopy and modeling, it is possible to understand organic matter’s interactions, processes, and their context in the ocean.
