Dr Ghazanfar Ali Safdar

Senior Lecturer in Computer Networking

Dr Ghazanfar Ali Safdar

Ghazanfar Ali Safdar received a BSc (Hons) in Electrical Engineering from University of Engineering and Technology, Pakistan in 1997. He subsequently received M.Eng in Computer Science and Telecommunications from University of Technology, Grenoble, France in 2001.

He was awarded a PhD from Queen's University Belfast, UK in 2005 for his work in the area of power-saving MAC protocols for the IEEE 802.11 family of wireless LANs.

He then worked from 2005-2008 with the same university as a Research Fellow involved in the security and authentication protocols for wireless networks.

Ghazanfar Ali is currently working as a lecturer in Computer Networking at University of Bedfordshire. He has also worked as R & D engineer with Carrier Telephone Industries (SIEMENS), Pakistan and Schlumberger, France
