This chapter traces Elizabeth “Liza” Badley’s life-long scientific identity and two major career transitions—from industrial chemistry to epidemiology and from the UK to Canada. Using the social chronolog(y) perspective on career transitions, it shows how ontic, spatial, and temporal dimensions jointly shape boundary crossing, changing conditions, and evolving positions in social space. The narrative highlights gendered role expectations that constrained options and sanctioned “role incongruity,” yet also spurred strategic moves and resilience. By linking identity, illusio, and symbolic capital, it explains why “once you’re a scientist, you’re a scientist for life” persists across employment statuses, with implications for academic work.
