Research in my group is focused on climate variability and climate change, which act as top-down drivers of Earth’s water cycle and other biophysical systems.

A primary focus of my work is paleoclimatology, the study of natural climate variability using environmental proxy records. Careful and considerate paleoclimatology promises deepened understanding of climate system dynamics and tree ring research has also proven to be very well suited to benchmarking extreme events.

Toward the end of reconstructing paleoenvironmental dynamics, we specialize in the development and interpretation of novel, high-resolution records from tree rings. My current projects are focused on water issues in California and the upper Midwest.

I am intrigued by the notion of climate services for improved adaptation capacity, and have long been interested in catalyzing connections between field-based research and decision making in natural resources management.
