Cella M. Sum is Postdoctoral Research Fellow at the University of Virginia's Digital Technology for Democracy Lab.
Her research focuses on technology, power, and resistance in labor and community contexts. Working at the intersection of HCI and STS, she uses qualitative and ethnographic methods to investigate how communities experience, navigate, and contest exploitative sociotechnical structures, such as data-driven systems, surveillance technologies, and AI infrastructure development. Using community-based participatory design methods, she works with affected communities to co-create more just alternatives. Her work has been published at CSCW, CHI, and Science as Culture.
Cella holds a Ph.D. in Human-Computer Interaction from Carnegie Mellon University and a Master's degree in Human-Computer Interaction and Design from UC Irvine. She is a member of Collective Action in Tech and a former tech worker organizer with Big Cartel Workers Union. She has over 15 years of industry experience in software engineering, UX research, and design.
