The Lab D’Andrilli researches carbon cycling from the perspective of dissolved organic matter (DOM) evolution biogeochemistry in marine, freshwater, terrestrial, and cryosphere ecosystems by investigating its quality and quantity. Aquatic, terrestrial, and icy environments can store and produce microscopic carbon-based materials (DOM). Humans are contributing to climate warming at a rate that will dramatically alter or reduce these reservoirs within a lifetime. In a warming climate, the release of glacial DOM into surrounding soils, rivers, and oceans is expected to increase greenhouse gases. In the Laboratorio D’Andrilli, we research the amount and type of carbon-based materials (or chemical energy) that are currently stored in glaciers and produced in rivers, soils, and marine waters, so we can predict its impact in the future. At the bulk and molecular-level, DOM composition and character reflect biogeochemical flux and cycling; therefore, identifying its chemical signatures may inform understanding of spatial and temporal patterns throughout aquatic and terrestrial networks. As humans, we can all can use this information to help reduce our carbon footprints and enforce healthy environmental policy in the future as the climate warms and sea-levels rise.

How have human beings impacted these waters?
We are identifying spatiotemporal patterns of fluorescent DOM in the West Fork of the Gallatin River, coupling gross primary production, ecosystem respiration, and DOM characterization as the system moves from peak to base flow conditions with increasing land-use development.

and Juliana D'Andrilli (LUMCON)
Are we getting the same answer?
This is a mass spectrometry (MS) DOM research project with 16 participating laboratories worldwide working towards an optimized protocol for best practices in the molecular assessment of dissolved organic matter using high resolution MS techniques (Fourier transform ion cyclotron resonance and Orbitrap MS instruments).
Led by: Jeffrey Hawkes (Uppsala University, Sweden)
and Juliana D'Andrilli (LUMCON)
What effects does legacy mining have on river ecosystems and how will the EPA's superfunded Upper Clark Fork River project change ecosystem regimes over the next 20 years?
We are a large team of 5 researchers seeking to identify the metabolic ecosystem regime changes with ongoing river restoration efforts. The team's multidisciplinary efforts are focused on metal concentrations, water quality (inorganic and organic carbon), DOM quality and metal complexation, hydrology, and biological dynamics from microbes to aquatic organisms, such as insects and fish.
Led by: Maury Valett (University of Montana), Mike DeGrandpre (University of Montana), Juliana D'Andrilli (LUMCON), Rob Payn (Montana State University), and Marc Peipoch (Stroud Water Research Center).
What DOM compounds fluoresce in natural and engineered ecosystems?
We are identifying the chemical compounds that can be detected with Excitation Emission Matrix Fluorescence Spectroscopy using direct measurement techniques in order to unify fluorescent community language that will minimize confusion and misinterpretations. Researchers, both young and old, let’s keep the conversation going and learn more from DOM photophysical properties that we can measure by EEMs.
