Theme 1 – Environment and Evolution
Research description: Elizabeth focuses on how fish and marine ecosystems respond to global climate changes. She uses the microfossil record of fish and sharks – their microscopic teeth and scales, preserved in deep-sea sediments – to reconstruct marine ecosystem dynamics across major global change events throughout Earth’s history, including global warming and mass extinctions spanning timescales ranging from 100 million years ago to the present. Elizabeth is most interested in how marine ecosystems function and what types of processes and environmental conditions drive evolution in those ecosystems. At Yale, she will focus on developing a multi-proxy record of a major and undescribed open ocean extinction event in order to better understand the structure of today’s marine ecosystems.
