Current Work

Colorado River Basin Discovery Farms

In a new project funded by the Colorado Water Conservation Board, I’m working with producers across the Colorado River Basin to explore how soil health practices affect water use and drought resilience. Each farm site is co-designed with the grower shaped by their questions, timing, and goals. We're collecting soil moisture, evapotranspiration, and carbon data to ground this work in both science and lived experience.

DIY Soil Health Assessments

This branch of my work is about giving land stewards practical, place-based tools to assess soil health without needing a lab. I’ve co-developed two guides that meet different needs: a DIY toolkit using household items, and a regionally specific in-field assessment guide for longer-term monitoring. Both are designed to build observational skills and support better decisions in the landscapes we live and work with.

Transdisciplinary Soil Health Systems Work

I serve on the leadership team of IN-RICHES, a regional innovation center focused on building the infrastructure needed to support regenerative soil health. Our work blends research, outreach, and policy with on-the-ground relevance, always rooted in the realities of land, water, and decision-making. We’re working to align scientific insight with practical change across the Intermountain West.

Colorado Soil Health Program

With IN-RICHES and Colorado Dept of Agricultre, I helped lead the research backbone of the Colorado Soil Health Program. We enrolled over 300 producers and worked across 35 farms and ranches to build a regional dataset on soil health, water, and management. Our team created standardized sampling protocols, co-developed the STAR field forms, launched a soil health Shiny app, and helped expand real-time soil moisture tracking across the state. The program was unexpectedly defunded in 2025, but the tools and data we built remain usable and relevant.
