Research in the Power Paleoecology Lab focuses on long term spatial and temporal scale ecosystem responses to environmental disturbance including  fire, climate change, and anthropogenic impacts. Current and recently completed research projects include studies in North America (Utah, Wyoming, Colorado), French Guiana, Bolivia, Brazil, and UK.


We use a variety of techniques to reconstruct long-term ecosystem dynamics including historical records, fossil pollen and plant macrofossils, diatoms, phytoliths, dung spores, micro & macrofossil charcoal analysis, stable isotopes (δ13C, δ15N, δ18O), and sediment geochemistry. 

Key research areas include interactions among vegetation, climate, disturbance regimes, and phenology.
