Primary Network Responsibilities: Field crew lead, Terrestrial Vegetation and Soils

Active Projects: Vegetation and Soils, Invasive Exotic Plants

Education and Areas of Expertise

I began working with the National Park Service as a volunteer with the Grand Canyon National Park Native Plant Nursery in 2015. Since then I’ve served two full terms with the Americorps Conservation Corps, working on exotic plant management, habitat restoration, vegetation monitoring, and vegetation mapping projects. I also have experience with botanical-garden plant nurseries. In my spare time I enjoy backpacking, climbing, biking, gardening, and otherwise appreciating the desert southwest.

Primary Network Responsibilities: Support for Desert Research Learning Center operations and activities, wildlife monitoring crew member.

Active Projects: Terrestrial Wildlife, citizen science, science communication

Education and Areas of Expertise

  • BA, Environmental Studies, University of Arizona

While studying at the University of Arizona, I co-founded a club that helped develop the grounds at the Desert Research Learning Center, and was involved with its citizen science program. Shortly after graduation, I started work full-time with the Sonoran Desert Network. I have been here for eight years managing the wildlife protocol and the grounds of the Learning Center. I have volunteered at pet shelters and animal hospitals for years, and in my spare time I hike, camp, make candles and soap, and paint.
