Our research group explores the molecular properties of dissolved organic matter (DOM) and soil organic matter (SOM) after land use and climatic changes with particular interest in the relationships between organic matter, metal transport, and uptake by microorganisms. Together with collaborators across academia, industry, and government, we are working to better understand how forest fires, forest harvesting, permafrost thaw, and agriculture impact the cycling of metals across terrestrial and aquatic continuums and the role that organic matter has on metal transport after disturbance.

We also specialize in microbial metabolomics where we explore the metabolic adaptations that algae have developed to aid in metal tolerance.  Our research group uses a suite of targeted and untargeted mass spectrometry based techniques to identify how humans are affecting fundamental biogeochemical cycles, and the implications for water quality.
