Dr. Rafiazka Hilman explores how urban sociotechnical systems shape social dynamics.
Cities are treated as urban sociotechnical systems, where residents, places of interest, digital platforms, and physical infrastructures interact—shaping how people use, adapt, and reshape technologies, and how technologies structure opportunities, mobility, and social interactions.
By linking social and spatial stratification, the work advances understanding of the complex interplay of digital and physical lives and supports adaptive, evidence-based policy design.
