My research interests center around carbon and nitrogen cycling in aquatic systems, and how these cycles are impacted by, and feed back into, global change. As a chemical oceanographer, isotope biogeochemist, and organic geochemist, the primary tools I use include the measurement of natural abundance isotopes and methods for the chemical characterization of dissolved organic matter. Current Projects: - Isotopic and chemical composition of DOM at the start of global overturning circulation - DOM composition and dynamics along oxygen gradients in the Eastern Tropical North Pacific oxygen deficient zone (ETNP ODZ) - Investigating sources and cycling of dissolved organic matter in coastal Western Canada using advanced isotopic and chemical characterization techniques - Tracing organic matter sources, composition and reactivity across Greenlandic fjord systems - exploring the influence of glacier type, climate and other environmental controls (https://cascades-expedition.science/projects/fjordoc/) Research Areas: Oceanography
