The project is supported by the Australian Research Council (ARC) DECRA project and supervised by Chris De Gruyter, Sarah Foster, and Afshin Jafari. Mehdi is also an experienced urban planner specializing in urban development policies and has published extensively on densification’s effects on urban resilience, urban form, housing development, and health (COVID-19).
