Catherine Davis, PhD

YIBS Donnelly Postdoctoral Fellow 2019-Present

My research interests fall within the broad areas of paleoceanography, paleoclimate, and paleontology.  Most of my work focuses on marine microfossils, how their geochemistry and morphology record and respond to climate and ecosystem change, and what such records can tell us about the influence of climate and marine ecosystems on one another.

Elizabeth Sibert, PhD

YIBS Hutchinson Postdoctoral Fellow 2020-present

My research focuses on how fish and marine ecosystems respond to global climate change using the microfossil record. I reconstruct ecosystem dynamics across major upheavals including global warming and mass extinctions events in the last 100 million years.  I am interested in how marine ecosystems function and what processes drive their evolution.  

Jennifer Kasbohm, PhD

NSF EAR Postdoctoral Fellow

My research uses a stratigraphic approach, combining detailed fieldwork with high-precision U-Pb zircon geochronology, geochemical, and paleomagnetic data. During my PhD, I generated the first U-Pb eruptive timeline for the Columbia River Basalt Group and I am currently testing the connection between this volcanism and mid-Miocene climate change in deep sea cores.

Liz Brabson

PhD Student, 2020- Present

I am broadly interested in the roles of ocean circulation and marine biogeochemistry in modulating the global climate system.
Sophie Westacott

Sophie Westacott

PhD Student            2016-Present

I’m interested in the silica cycle, as it relates to the evolution of siliceous organisms. I’m also interested in fossil preservation and how it affects our understanding of the fossil record.
Daniel Gaskell

Daniel Gaskell

PhD Student            2016-Present

I am broadly interested in how marine ecosystems respond and adapt to environmental pressures, with a view towards understanding how to best manage modern-day marine ecosystems and natural resources. In particular, I have developed models to integrate our mechanistic understanding of biological and geochemical processes in order to interpret geochemical signals from the past.  

Jack Shaw

Jack Shaw

PhD Student            2017-Present

I work at the intersection of paleoecology and taphonomy. In particular, I’m interested in how community structure has changed across the Phanerozoic through the lens of ecological network analysis.
