Research Interests

Recent (late Quaternary to modern) environmental change in the marine environment, utilizing the geochemistry of microfossils and corals to understand:

• rates and magnitude of climate change,
• response and adaptation of marine species to environmental change
• role of methane emissions in climate change and marine geological processes
• impact of climate change on carbon cycling and oceanic anoxia
• connections between climate change in marine and terrestrial environments
• anthropogenic impacts on the ocean system, including ocean acidification and anoxia

Research utilizes several proxies in the paleoceanographic record as indicators of temperature and environmental change, such as:

• stable isotopes (δ¹⁸0, δ¹³C. δ¹⁵N)
• trace elements (Mg/Ca, Sr/Ca, Cd/Ca)
• radiocarbon
• foraminiferal species assemblages
