Interests My main research interest is to develop end-to-end network diagnosis techniques to uncover dynamic network properties (e.g. congestion information, bottleneck equivalence, loss rates, topology, etc.) in a near real-time fashion. This information can be used to characterize the Internet dynamics and to dynamically adapt the control strategies of massively accessed Web servers (e.g. congestion control, redirection strategies, etc.) for a more efficient utilization of network resources.

A Framework and Toolkit for the Effective Measurement and Representation of Internet Internal Characteristics: 
My Ph.D. research addresses the challenge of providing efficient, accurate and compact network 
models that are capable of uncovering shared network resources across multiple end-points. In my Ph.D. dissertation I introduced a framework that infers, labels and integrates metric-induced network topologies connecting network end-points. The framework applies to a broad class of metrics encompassing loss rate, delay, bandwidth ? I also introduced a new set of end-to-end unicast probing mechanisms that are capable of uncovering different network properties. These mechanisms correctness have been validated through analysis, simulation and Internet deployment. They have been shown to be of great benefit for network-aware applications and for Internet characterization. (Co-advisor: Prof. John Byers)

Masters' Thesis                                                                          Advisor: Prof. Amin Shoukry 
Speech Recognition Using Neural Networks:
In my masters' thesis I developed a hierarchy of time-delay Neural Networks and single layer 
Perceptrons that were used for speech recognition

Research Fellow Fall 1998 to present                                           Advisor: Prof. Azer Bestavros

Designed, analyzed and implemented a framework (MINT) that is capable of diagnosing Internet 
dynamics. The MINT framework has been used as part of the MASS and WING networking groups 
at Boston University to analyze and characterize Internet performance and to design content delivery protocols for massively accessed web servers. This work resulted in papers at INFOCOM'02, PAM'02, ICNP'00 and a couple of other papers under review.

Clemson University                                                                                              Clemson, SC
Research Assistant Spring 1996 to Fall 1997                                      Advisor: Prof. Roy Pargas

I was responsible for implementing a Balanced Inventory Flow Replenishment System (BIFRS) for the Department of Defense. BIFRS is an enterprise-wide constraint management solution to optimize items distribution on time and at lowest total cost. 

Alexandria University                                                                                    Alexandria, Egypt
Research Assistant Fall 1992 to Summer 1994                                 Advisor: Prof. Amin Shoukry

Experimented with several supervised and unsupervised Neural Network models for the speaker independent recognition of speech utterances. Different Neural Network objective functions, methods of features extraction and ways of end-pointing speech utterances have been investigated. A new hierarchy consisting of modules of Time-Delay Neural Networks (TDNN) and Single Layer Perceptrons (SLP) has been proposed, analyzed and implemented. This work resulted in a paper at NSRC'95.
