I am an organic geochemist interested in understanding biogeochemical cycling and perturbations to these cycles. I specialize in carbon cycling, specifically in the transport and quality of terrestrial organic matter in aquatic systems and am particularly interested in constraining fluxes between environmental interfaces. I first became interested in studying aquatic systems as toddler, and been devoted to studying environmental science ever since then. I received a BSc in Oceanography with an emphasis in Chemistry in 2011 from the University of Washington and my PhD in Chemical Oceanography from Texas A&M University in 2016.
I am especially interested in studying areas most sensitive to climatic changes, such as boreal forests. My research focus in the BBERG is to characterize the impacts of climate and seasonality on dissolved organic matter transport from terrestrial to aquatic systems using modern organic geochemical techniques. I plan to help solidify the flux, composition, and degradation potential for DOM transported from the terrestrial to aquatic environment in boreal forest ecosystems with respect to a changing climate. I will combine a variety of analytical techniques to characterize organic matter across this continuum, and will help elucidate the varying mechanisms responsible for DOM composition exported from soils to aquatic systems.
