Sand Island, one of the first islands on the atoll to have successfully eradicated coconut palms, which were quickly replaced by a healthy Pisonia forest with abundant shorebird life.

I use a range of proxies (plant macrofossils, pollen, charcoal, stable isotopes) to interpret climate and landscape change over centennial to millennial timescales. Current topics include responses to abrupt permafrost thaw, sea-level rise, sea-ice retreat, and centennial-scale land-use change.

Reconstructing Vegetation and Climate Histories on Palmyra Atoll to Assist with Climate-Smart Adaptation
Project Overview Palmyra Atoll National Wildlife Refuge (NWR) is a critical nesting site for seabirds in the central Pacific Ocean, with ecosystems that are regularly impacted by the El Niño Southern Oscillation (ENSO). Researchers supported by this Pacific Islands CASC project aim to understand how past ENSO-driven climate variability and human activities have affected vegetation and wildlife. T
Holocene and Modern Drivers of Wetland Change
On a global scale, wetland systems have been affected by climate extremes, changing sea level, and population growth, reducing their capacity to moderate storm surge, filter contaminants, store carbon, and provide habitats for fish and wildlife. This research takes a long-term perspective on the resilience of wetlands to a range of climatic and human-induced changes and provides critical data to...
Wetlands in the Quaternary
Wetlands accumulate organic-rich sediment or peat stratigraphically, making them great archives of past environmental change. Wetlands also act as hydrologic buffers on the landscape and are important to global biogeochemical cycling. This project uses wetland archives from a range of environments to better understand how vegetation, hydrology, and hydroclimate has changed on decadal to multi...

Thawing Peatlands, Alaska
Cores were collected from various areas of thawing permafrost-peatlands in Alaska. Permafrost thaw results in ground subsidence and inundation that kills black spruce and other understory plants living on the permafrost plateau.
