My primary research aim is to assess impacts of climate change on land-water-atmosphere interactions. I focus on terrestrial and aquatic ecosystem links, primarily by assessing biogeochemical cycles across scales, spanning from a broader watershed perspective to the underlying microbial processes. I utilize a mix of field and lab based methods, combined with remote sensing and sensor technology to broaden scientific knowledge across space and time. While I have a broad interest in aquatic biogeochemical cycles, I specialize in assessing greenhouse gas dynamics.
