Research focuses on Cenozoic lake sediments, biotic responses to climate change and pollution, fossil conifer resins, and other ecological problems requiring a historical perspective.
In a general sense, our objective is to understand environmental dynamics on geological to societal timescales through the interrogation of natural archives. This is a fairly open-ended research agenda, but one that has potentially far-reaching consequences for understanding planetary futures.
At present, some themes that are being pursued include:
Freshwater siliceous algae (diatoms and chrysophytes) as proxies for environmental change on Cenozoic, Quaternary, and recent timescales
Applictions of fossil conifer resins (resinite and amber) in paleobotany and paleoclimatology: inclusions, geochemistry, and diagenesis
Characterizing the Holocene-Anthropocene transition: non point-source anthropogenic impacts in remote ecosystems, recent climate change, and synergistic effects associated with global biogeochemical imbalances
Glacial history and late Quaternary paleoenvironments of the Arctic
Paleogene lake sediments: paleobiology, geochemistry, and geochronology
Geoarchaeology and paleoclimatology of the Andes, especially pre-hispanic archaeometallurgy
Paleoecological applications of visible and infrared spectroscopy
