Bio/Research
Keller’s primary research interests focus on major catastrophes in Earth’s history in the broadest sense, including the biotic effects of catastrophes, such as mass extinctions, meteorite impacts, major volcanic eruptions, rapid climate changes and ocean acidification. Her research integrates paleontology, stratigraphy, geochronology, sedimentology and geochemistry in reconstructing past environmental changes associated with or leading up to mass extinctions.
Keller is well known for her contributions to the Cretaceous-Tertiary mass extinction controversy. She has contributed in diverse areas, including a global quantitative analysis of the nature, rate and tempo of the mass extinction, stratigraphy and age control, climate and sea level changes, the distribution and age of diverse ejecta material related to impacts and Deccan volcanism. Her latest work on Deccan volcanism has concentrated on age dating of the main eruptions at and near the KT mass extinction in India and documenting the effects of this volcanism worldwide. Her work is largely the result of interdisciplinary collaborations with an international team of scientists and students.
