Katrina Johnston-Zimmerman is an applied urban anthropologist who has spent her career arguing that the city is not just a collection of buildings and hard spaces, but a manufactured habitat for the human species - an ecosystem that we desperately need to start loving again. A former BBC 100 Women honoree and co-founder of the “Women-led Cities Initiative”, Katrina has built her career by bridging the gap between academic theory and the pulse of the street, using spatial ethnography to map the invisible social desires of a community. With her work, she is proving that feminist urbanism is far from a niche advocacy, but is instead a rigorous, necessary framework for creating safer, more resilient, and more compassionate cities. She has applied her expertise to a range of fields including non-profit organizations, academic research and education at universities in Philadelphia and Stockholm, consulting for Business Improvement Districts and architectural firms, and working on data privacy regulations in public space for the Smart Cities department in Philadelphia.
