Research

• Paleoceanography
• Paleothermometry
• Paleo-CO₂ variations
• Biomarkers (particularly alkenones)
• Isotope ratio monitoring gas chromatography/mass spectrometry (irm-GC/MS) methodology

My work focuses on paleothermometry and paleo-CO₂ variation reconstructions. Specifically, I employ alkenone and foraminiferal biomarker geochemical isotope analysis as a tool to quantify and examine variations in sea surface temperature (SST) and atmospheric CO₂. Within the diverse category of organic biomarkers, I focus on alkenone unsaturation as an indicator of SST and atmospheric pCO₂ as well as foraminiferal ẟ¹⁸O as an indicator of SST. My goal is to create paleorecords of SST and atmospheric pCO₂ from the late Pleistocene through the present in the central sub-tropical equatorial Pacific Ocean to compare with existing paleorecords produced from other climatological proxies. Currently, my method uses irm-GC/MS to analyze alkenone unsaturation and foraminiferal ẟ¹⁸O.
