Research Interests

My research interests center on the interaction between climate and terrestrial ecosystems: how climate change effects and is affected by ecosystem change. In my work, I use measurements of naturally occurring light stable isotopes and modeling to identify and characterize these effects in the modern and in Earth’s geological record.
