Introduction
I am Associate Professor of Digital Media & Design Computing at the Department of Architecture, American University in Cairo, Egypt. I received my BSc (2000), MSc (2004) from Ain Shams University, and PhD (2011) from Georgia Tech, USA. I have publications in Computer-Aided Design, Advanced Engineering Informatics, Automation in Construction, IJPEDS, IJAC, CAADFutures, ACADIA, CAADRIA, eCAADe, PLEA, IBPSA, DRS, IASDR, ASCAAD, SIGRADI. My recent research involves a variety of topics, including the development of low-cost soft adaptive façade systems using hygroscopic properties of wood, automated post-occupancy space management using BIM and GIS, and the design and fabrication of complex facades using robotic depositing and multi-point forming.
