I study past climate and biogeochemical cycles.
I like to dig around, both literally and figuratively.
Geochemists never die, they only reach equilibrium.

Our new study is out in @natcomms.nature.com!
We present a glacial CO₂ reconstruction from the Chinese Loess Plateau over the past 2.6 million years and explore what it reveals about climate sensitivity during the Pleistocene.

Land snail shells are widely used to reconstruct past rainfall δ¹⁸O. But what if snails aren't just drinking rain? 🌧️🐌
I tested this using isotope modeling—and dew plays a much bigger role than we thought.

I am pleased to share this work showing that atmospheric vapor can be directly utilized by clay-rich vertisols with potential implications towards drought mitigation.

Today, as the Trump administration issued mass layoffs to NOAA scientists, its worth remembering Syukuro Manabe, whose groundbreaking climate models, presented to the Senate in 1985, predicted the very changes we now face.
Attacks on science threaten our future.
