This study investigates how tenure-track faculty from historically marginalized groups in the environmental sciences approach science communication based on their self-identities. A thematic analysis of 28 in-depth interviews with U.S.-based participants using the Communication Theory of Identity and Border-Crossing Theory was conducted to explore the interrelation of layers of identity, the identity gaps participants experience, and their communication practices. The results show that communication merges fragments of identity not to form a fixed identity, but to create an evolving consciousness about who you are and how you communicate. Implications for science communication training are discussed.
