Monohan Lab Group

Hydrologic Surveying in Meadows

Welcome to the Monohan Lab Group (MLG), a resource for prospective graduate students, current and former students of Dr. Carrie Monohan, Science Director at The Sierra Fund (TSF) and Adjunct Professor at California State University, Chico’s Geological and Environmental Sciences Department.

This page highlights research conducted by current students and alumni to enhance ecosystem and community resiliency in the Sierra Nevada, and provides a key opportunity for members to contribute to and benefit from continued collaboration with TSF and our partners.

We look forward to co-creating this resource with the researchers formerly or currently working to enhance scientific understanding of unique Sierra issues.

Prospective students should contact Dr. Monohan at carrie.monohan@sierrafund.org for more information.
