Research Description

Cindy describes herself as "a plant ecologist who works in the past" and studies the response of plants and their communities to major environmental change and the possible evolutionary consequences. Her primary research is focused on the end-Permian biotic crisis and its aftermath, and the transition from a glacial-dominated world to an ice-free one during the Late Carboniferous to the Middle Permian.
