I am interested in using observational data and numerical models to study how physical and biogeochemical processes affect hypoxia and acidification in coastal and estuarine systems. Specifically, my work involves (1) the impact of different sources of nutrients on Chesapeake hypoxia, (2) the impact of local human activities and global climate change on Chesapeake Bay carbonate system from diurnal to decadal time scales, and (3) translating the research into usable and actionable information for stakeholders via outreach activities.
