About
I am a forest biometrician and the founder and principal of Siskiyou Biometrics, an independent forest biometrics practice based in Ashland, Oregon. The practice provides review, design, and strategy for the forest inventory and biometric systems supporting timberland investment and forest management decisions.
I hold a BS and MS in forestry from Michigan State University, where my research centered on small area estimation and Bayesian methods for large forest inventories. I am the original author of rFIA, an open-source R package built to simplify access to the US Forest Inventory and Analysis (FIA) database, and the lead author of peer-reviewed research on forest change in the western United States, published in Nature Communications. Before founding the practice, I spent nearly five years at Campbell Global leading the forest biometrics and inventory team, supporting acquisitions and timberland valuations worldwide and operations across four countries. I have held every seat at the table where a model meets a consequential decision: building the estimators, publishing the methods, and relying on them under fiduciary pressure.
I also founded and run Rogue Evergreens, where we steam-distill and bottle single-species essential oils and hydrosols from Pacific Northwest conifers by hand.
