Earth’s crises under the microscope – biodiversity and
climate through deep time

I am a Royal Swedish Academy of Sciences Research Fellow supported by a grant from the Knut and Alice Wallenberg Foundation

My project uses high-resolution palynological (pollen) analysis of sediments, and a broad spectrum of geochemical procedures to resolve the timing, rates, and causes of Life’s most profound catastrophes.

Causal hypotheses for other extinction events in history of life are tested using methodologies successfully employed by my research team over the past four years on the Cretaceous-Paleogene (KT) mass-extinction event. The now rather well-resolved patterns of biotic extinction and recovery at the KT boundary provide a model system for interpreting biotic turnover during other crises for life on Earth. Further, climate change during longer time intervals are assessed by interpreting the relation between vegetation and climate change during the Miocene in Scandinavia.
