In this study, we explore the identity development of PhD graduates transitioning into non-researcher roles. Through the conceptual lens of identity-trajectory theory and based on interviews with 26 PhD graduates from three leading research universities in Hong Kong, Macau and Taiwan, we analyse their identity-trajectory development after their transition to non-research employment. The findings show that PhD graduates develop their identity trajectories based on their existing sense of researcher-self through a variety of practices that involve intellectual, networking and institutional dimensions. Individual agency plays a key role in overcoming structural constraints in the workplace, yet its level varies according to one's willingness to pursue a non-research career. The findings highlight the fluidity in identity development and the role of the researcher-self as a positive legacy of doctoral training, including for PhD graduates taking non-researcher roles.
