Research Interests
I study the evolution of Earth’s climate system on sub-millennial to orbital timescales using geochemical proxy records derived from marine sediments. My studies are relevant to IPCC concerns that ongoing climate change is accelerating polar ice cap melting and global sea level rise.
My research is divided into three focus areas: 1) Cenozoic climate evolution/Antarctic cryosphere development, 2) Role of the high-latitude oceans in Glacial-Interglacial carbon cycling, and 3) Antarctic Holocene climate variability.
I employ inorganic (trace elements in foraminifers and marine sediments, 14C, diatom δ30Si, foraminifer δ18O and δ13C) and organic (lipid biomarker) geochemical techniques and micropaleontologic analyses as appropriate to the processes I am investigating. My multi-proxy approach enables me to address a broad range of climate and biogeochemical problems
