Dr Hristova is a historian of media and culture. Her research is at the intersection of media and communication history, critical whiteness studies, gender studies, social movements, and critical approaches to methodology. Dr Hristova's previous research examined the history of women's labour in media and communication research and its implications for disciplinary foundations and research methodology. Some of this research was published in The Ghost Reader: Recovering Women's Contributions to Media Studies (Goldsmiths, 2024) and in the International Journal of Communication (2022). 

Dr Hristova's current research project is Graffiti, Politics, Place, which seeks to determine the ways in which graffiti function as a form of political and cultural communication, heritage making and preservation in the postcolonial/devolved North Wales. Graffiti, Politics, Place has been part funded by Taith.

Dr Hristova teaches modules on visual culture, gender, race, research methods, media ethics, and social movements.

Dr Hristova is a current recipient of WREC funding to organise and run Write Now! Summer 2025 writing retreats for Early Career Researchers at Bangor University.
