The Quaternary period records dramatic examples of abrupt climate changes whose effects propagated rapidly across Earth systems. Although the timing and rates of many of these changes have been refined over recent decades, geologic archives continue to reveal new insights into how ice sheets, hydroclimate, sea level, and solid Earth processes responded to these rapid forcings.

Our research resolves these changes through field-based studies paired with high-precision uranium-series and radiocarbon dating. By integrating diverse geological archives, we reconstruct how climate-driven changes emerged across the planet. These insights from our past climate are important anchors for understanding future climate and environmental change.

Current research directions:

1. Previously unrecognized ice sheet and mountain glacier responses to abrupt climate forcing
2. Abrupt hydroclimate changes and rainbelt migrations across the mid-latitudes and tropics
3. Cave speleothems as archives of past climate and environmental change
4. Reconstructions of past sea level change
5. The interplay between tectonics, volcanism, and climate

I am building a diverse, multidisciplinary research group that values curiosity and collaborative problem solving, and I welcome students and collaborators interested in field-based research and developing new directions across Earth systems. Prospective graduate students and postdocs are encouraged to connect to discuss research opportunities.
