Guest doctoral researcher  (02/2026-03/2026)


PhD candidate enrolled in the joint doctoral program of TU Dresden and the Leibniz Institute of Ecological Urban and Regional Development (IOER), known as the Dresden Leibniz Graduate School (DLGS), in Germany.
Her PhD research focuses on the reuse of vacant residential buildings. During the initial phase of my work, I developed a conceptual framework categorizing challenges related to this process, which was empirically tested through fieldwork in Cairo as a primary case study. The Cairo case
study yielded two key findings: (a) the emergence of new sub-codes insufficiently addressed in the
existing literature, and (b) the contextual irrelevance of certain initially assumed sub-codes.
