As Chief Technology Officer in The Nature Conservancy’s California Chapter, Matt is responsible for research, strategy, and application of technology solutions to serve the Conservancy’s mission. He has 20 years of experience in the field of geospatial technology that encompasses geographic information science, remote sensing, GPS, and drones. He currently leads a team responsible for spatial planning, analysis and technology focused solutions that can have big impacts in social-ecological systems.

Before joining the Conservancy, Matt was the Director of Geographic Information Systems at Space Imaging Corporation where he worked on a variety natural resource mapping projects and developed spatial models to determine fire risk for the Insurance Services Office. He has a B.A. in Geography from University of California, Berkeley and an M.A. in Geographic Information Science and Environmental Planning from San Francisco State University.

What Matt is working on now:

I'm currently working on ways that AI can be utilized in various aspects of the Conservancy's work with a deep focus on fisheries this year. And I'll be going back to my geospatial roots and supporting a global scale mapping effort of MPAs that will leverage the Conservancy's deep network of GIS practitioners in field.

Opportunities to improve fisheries management through innovative technology and advanced data systems

Darcy Bradley, Matt Merrifield, Karly M. Miller, Serena Lomonico, Jono R. Wilson, Mary G. Gleason

A lack of fishery data leads to uncertainty about stock status, which may compromise and threaten the economic and food security of the users dependent upon that stock and increase the chances of overfishing. Recent developments in the technology available to collect, manage and analyze fishery-relevant data provide…
