Short Biography

I obtained my Bachelor's and Master's degrees from Cairo University, Egypt in 2001 and 2003 respectively.
In 2007, I obtained my PhD from Konstanz University, Germany. I did my PHD work under the supervision of Prof. Marc Scholl and Prof. Torsten Grust.
In 2007-2008, I worked as a researcher at National ICT Australia (NICTA), NRL lab.
Currently, I am a Senior Research Associate / Lecturer in the Service Oriented Computing Group (SOC), The School of Computer Science and Engineering (CSE), University of New South Wales (UNSW) and an Adjunct Lecturer with the Department of Computing in the Division of Information and Communication Sciences at Macquarie University.

Research Interests

Graph Data Management and Social Networks.
Data Centers and Data Management in Cloud Computing.
Web Databases and Web 2.0 Technology.
Service Oriented Computing and Web services.
Business Process Modeling and Management.

Research Projects
