I am broadly interested in forest response to climate change, past and present. I work in California’s mixed conifer forests where disturbance regimes, especially wildfire, drive community composition and ecosystem function. Currently, I am focused on leveraging reconstruction techniques from paleo-ecology to compare modern forests to those from the late-Holocene and Euro-American settlement. My field sites are located in the Six Rivers National Forest, CA. My PhD research has been funded through a UC Berkeley Fellowship for Graduate Study, a Hellman Graduate Scholarship, the W.C. Rosencrans Fellowship for forest management research, and a Philomathia Graduate Fellowship in Environmental Science.

In 2019, I was awarded a CAL FIRE Forest Health Research Grant to study carbon storage in pre-suppression forests. This work directly ties to Senate Bill 901 that instructs CAL FIRE and the Air Resources Board to develop “a historic baseline of greenhouse gas emissions from California’s natural fire regime reflecting conditions before modern fire suppression.”

As of 2020, I joined the research team leading Project 1 at the Center for Ecosystem Climate Solutions, an initiative funded through California’s Strategic Growth Council under Gov. Gavin Newsom. We are developing tools to map ecosystem properties and services and lay the technical foundation for subsequent projects.

I am also convinced that scientific research should not remain abstract and unsullied by real-world problems, which has led to my interest in the application of science to recalcitrant environmental challenges. I was part of a team of scientists working on California’s 4th Climate Assessment. Published in 2018, this document is the largest collection of actionable climate change research in California’s history. I contributed to the regional chapter on Sierra Nevada.

Before starting a PhD at UC Berkeley in 2016, I received two masters degrees — an MSc in Water Policy and an MSc in Biodiversity Conservation — from the University of Oxford where I studied as a Rhodes Scholar, and a BA in Chemistry from Smith College.
