个人简介
Keller’s primary research interests focus on major catastrophes in Earth history, including the biological effects of mass extinctions, meteorite impacts, major volcanic eruptions, rapid climate change, ocean acidification, and oceanic anoxia events. Her research integrated paleontology, biostratigraphy, geochronology, sedimentology, and geochemistry in reconstruction of past environmental changes associated with or leading up to mass extinctions and major evolutionary turnovers. Most of this work relies on analysis of foraminiferan fossils, or tiny carbonate shells that represent the remains of marine organisms. Using taxonomic, chemical, and isotopic signatures preserved in these fossils, Keller has been able to document the timing and rate of environmental change on Earth’s surface.
