As an urban environmentalist and political ecologist, Corbin examines the relationships between society and nature within the built environment by investigating the concept of the green city within the context of the United States. Her dissertation focuses on how the relationships between race, class, and access to green space have changed from 1960—prior to the Civil Rights Acts—to 2019, after Oakland, California began establishing its sustainability agenda and during an intensifying gentrification process. Corbin questions how environmental policies and practices in green cities are impacting the lived experiences of low-income residents and communities of color and their access to public green spaces today and what that could mean for future populations living in green cities. As the chair of the City of Oakland Parks and Recreation Advisory Commission (PRAC) Corbin serves her community through civic engagement by researching, reporting, and making recommendations to City Council on Park and Recreation policies and as the PRAC liaison to three Recreation Advisory Councils, the local community park stewards. Corbin is also an executive committee member of the California Outdoor Engagement Coalition focused on getting youth who reflect the overall demographics of California into the outdoors by providing transformational experiences.
