Sarah Ivory is an ecologist and geologist who uses fossil pollen records to better understand past ecosystem change in order to inform future conservation strategies. She also works with models and remote sensing data to observe the processes that drive tropical ecological change and vegetation responses to climate in the past. This work focuses on vegetation and climate history from the recent past to millions of years ago in order to evaluate future range changes and land-use impacts in hotspots of global biodiversity.
