Zachary Dove

Research Fellow

Zach is a PhD student in the Politics Department at University of California, Santa Cruz, where he studies public engagement, emerging technologies governance, and global environmental politics. His dissertation research explores how different forms of engagement matter for emerging technologies governance, specifically how engagement can enhance or erode justice in solar geoengineering governance. He is enthusiastic about supporting DSG’s work to develop inclusive and effective governance capacity building programs in climate vulnerable communities. He received a BA in political science from Western Washington University, where he was also active in supporting farmworkers and First Nations in the Pacific Northwest region.
