Exploring the intertidal zone, one species at a time.
I photograph and document marine life along the California coast, build tools for naturalists, and share the hidden world of tidepools through images and data.
I'm a naturalist and photographer with a focus on California's intertidal ecosystems. My iNaturalist profile documents thousands of species observations across rocky shores, kelp forests, and sandy beaches.
When I'm not in the field, I build open-source tools that help other naturalists document, map, and manage their observations.
