General Interests

Paleoceanography; chemical oceanography; trace metal chemistry; foraminiferal trace elements; carbon cycling; ocean circulation; glacial-interglacial cycles

Ph.D. Research

My current work focuses on reconstructing the carbonate ion history of the eastern North Atlantic over the pat 500,000 years using benthic foraminiferal B/Ca. By pairing B/Ca with other proxies, such as d13C, we can better understand changes in ocean circulation and carbon cycling on interglacial-glacial timescales.
