Jessica Rodysill



Jess Rodysill is a Research Geologist specializing in reconstruction of past environmental conditions using geophysical and geochemical properties of lacustrine sediments.  The goals of this work are to improve understanding of the mechanisms that drive natural hazards at the regional and local scales, which will aid in improving preparation for hazards and disaster mitigation for vulnerable populations.  Jess is the Project Chief of the Natural Drought and Flood Histories from Lacustrine Archives project, which utilizes lacustrine sedimentology to reconstruct floods, droughts, and hurricanes. She leads the USGS Holocene Synthesis working group, which integrates multi-proxy data from North American continental archives to reconstruct spatial patterns of wet, dry, warm, and cool conditions through time.  This research is used to better understand the mechanisms driving natural climate variability and millennial and centennial timescales and to improve computer model forecasts.  Jess is leading a pilot study in the central and eastern United States aimed at understanding the long-term, millennial-scale history of earthquakes at active fault zones to better assess the risk of future earthquakes.
