Julian Reyes is the National Coordinator for the USDA Climate Hubs program. In this role, he provides connection and cohesion across the regional Hubs, integrates Climate Hub work across USDA agencies, coordinates with other climate networks, and engages with stakeholders. Prior, Julian was a AAAS Science and Technology Policy Fellow at the U.S. Department of State in their climate change office.

Julian was also a Climate Hub Fellow with the USDA Southwest Climate Hub from 2016 to 2019.
