Terrestrial Paleoclimate and Earth Systems Research

Understanding interactions between the biosphere, atmosphere and lithosphere through time

Our research is focused on on understanding how earth's climate and ecosystems have changed through time. We seek to understand the links and feedbacks between the biosphere, atmosphere, and lithosphere to examine how earth's past can help inform its future. We use a combination of organic molecular biomarker and stable isotope measurements, coupled with field studies, and numerical models in order to build an understanding of the Earth system. We are particularly focused on studying past climates to understand how the Earth’s climate may behave in the future as greenhouse gases increase in our atmosphere. Field sites include western North America, east Asia, and South America.

  • Fieldwork in the White Mountains of NH During COVID-19
    Chris Sparacio (’24 PhD) and Michael Hren met up with fellow UConn Professor Will Ouimet to collect a new drill core from an alluvial fan in the White Mountains. This was a unique field sampling expedition and COVID-19 required social distancing measures, but it was a great chance to get into the field for some […]

  • Welcome to Baylee McGinnis, M.S. 2022
    We’re happy to offer a warm welcome to Baylee McGinnis, a new M.S. starting in Fall 2020. Baylee graduated from Smith College in the Spring of 2020 and spent the summer working in Washington State. She will be working on a new project looking at the links between ecosystem and hydrologic change across the Eocene-Oligocene […]
