Bryan DeAngelis is the Lead Scientist for the Ocean Recovery Strategy of California’s Oceans Team. He also continues to work across TNC’s North America Region, providing strategic and technical leadership to coastal conservation and restoration work across the country and globally. Bryan has a proven history leveraging science to launch and manage innovative ecologically and socially meaningful coastal restoration programs. These range from helping launch the Gulf Corps Program in the Gulf designed to implement habitat restoration work across all five states while simultaneously advancing employment opportunities for young adults; to the Pacific Coast Ocean Restoration Initiative in California which is one of the largest, ecosystem-based, multi-partner restoration programs ever launched on the west coast of the U.S. Recently, Bryan has worked to advance California’s ability to implement habitat restoration for key biogenic habitats, including kelp, seagrass and oysters by advancing key science bottlenecks, and raising the ambition for scaled restoration through strategic policy, science and partnership-led initiatives. 

Prior to joining TNC, Bryan worked at NOAA’s Restoration Center where he worked to advance both community-based and Natural Resource Damage Assessment projects. In his free time, Bryan enjoys spending time with his daughters, surfing and coaching youth soccer.

What Bryan is working on now:

Most recently, Bryan has been helping lead TNC California’s Ocean Recovery Strategy by providing thought leadership and guidance to our team to launch new and innovative science and on-the-ground projects focused on advancing kelp, oyster and seagrass recovery and restoration throughout the state.  He is also currently serving as a project and science lead on the Pacific Coast Ocean Restoration Initiative, working with over a dozen partners to ensure the PCOR Initiative results in impactful science that propels the state’s ability for sustainable ecosystem restoration for rocky reef habitats. Bryan is also contributing to the Conservancy’s habitat and fisheries goals by leading an effort to advance the science and applicability of estimating and applying the augmented production of fish and invertebrates from seagrass habitat in San Diego Bay.  Outside of California, Bryan works closely with the Conservancy’s USGR staff and has developed and manages two separate large-scale cooperative agreement with NOAA’s Office of Habitat, including a recent $25M institutional award with NOAA which is funding TNC to implement several natural resource damage assessment related restoration projects around the country.
