This inquiry both builds on and extends exploration into gendered research through a focus on researcher vulnerability and its associated ethics. We discuss six critical vignettes across Western and Eastern contexts in which female researchers are "undone" and subsequently "redone" during their research endeavors. We draw upon Butler's work on gender and vulnerability, theorized as a subset of precarity. Attention is drawn to attempts to reframe, understand, and mobilize vulnerability differently, as a form of resistance, research activism, and emancipatory enactment. We propose agentic vulnerability as speaking to felt moments of vulnerability experienced in field research. We extend this contribution into a theorization of the researcher as activist, outlining practical applications of this concept. Ultimately, we seek to reposition agentic vulnerability in institutional research as a source of new ethics, research practices, and activism.
