I am primarily interested in the following research areas. However, I am always ready to explore new directions and fields of study.

sustainable computing

I am working on a new paradigm of computing systems, entitled "energy, data, communication -aware computing," acronym ED-CAC. The ED-CAC paradigm mandates that when developing data, task, and communications schedulers (both low and high-level), workflow managers, and higher-level application throughput maximizes, tasks (jobs), data (cache and memory), communications, and energy consumption must be treated equally important. An autonomic ED-CAC is a very challenging proposition that encompasses topics, such as scheduling theory, data management, OS, data manipulation, optimization methodologies, system programming, data staging, placement, and replication, communication theory, and systems engineering. I have a group of researchers working of the aforementioned paradigm. If you are interesting in collaboration, then please do contact me. I will be very happy to share our group's expertise with you.  Below is a list of representative publications.

 

social networking

I am actively working on utilizing social networks for large-scale information integration, which can be readily deployed in situations that demand immediate attention, such as natural and man-made disasters, and search and rescue. I also am very interested in using social media for classroom instructional use, and malicious behavior detection. The aforementioned encompasses research areas, such as data mining, ontology, data manipulation, data staging, distributed systems, optimization techniques, and communication theory. My research group's expertise on social networking is increasing rapidly. Please do contact me if you would like to collaborate and share your expertise. Below is a list of representative publications.

 

robust backbone networks for cyberinfrastructures

I am interested in studying the impact of  natural and man-made disasters on multi-layer network backbones, and establishing a robust and intelligent survivability framework for provisioning quantifiable multi-faced and multi-tiered recovery across the network layers (both packet and circuit switched). The work entails the analysis of various types of activities and their affect on network backbones, developing robust routing algorithms, and conceiving distributed recovery mechanism. I am working with a diverse set of researchers that have expertise in telecommunications, signal processing, robust algorithm development, distributed and discrete optimization methodologies, and communication theory. Please do contact me if you would like to collaborate on the aforementioned research topics. Below is a list of representative publications.

 

reliability

I am interested in studying critical cyberinfrastructures, which have stringent reliability requirements. It is challenging to pursue absolute reliability (robustness, trust, and security) for a system as it becomes computationally expensive to implement. As a consequence trust level assurance is opted as a more balanced approach. I am developing rational models for trust that can easily be incorporated into current solutions (as a new approach for security). Developing such models entails development of: (a) trust assurance methodologies, which provide the required steps covering end-to end trust estimation applied to a critical cyberinfrastructure, from the observed system modeling to the trust presentation and monitoring; (b) distributed policy elaboration, which considers the observed infrastructure in a dynamic context, i.e., policies (at all levels) will be in the core of the trust estimation processes; (c) reputation mechanisms, which are needed to construct a reputation model to be exploited in the trust estimation; (d) aggregation strategies for trust values, which will be estimated based on the knowledge (reputation based) and the experience (learning mechanism) of the entities within the systems. I have studied and currently studying the aforementioned issues in the context of reliable data sharing, replication, and data intensive computations. The emphasis there is to provide data accessibility schema that is reliable and trusted during the lifespan of the system. Please do contact me if you would like to collaborate on the aforementioned issues. Below is a list of representative publications.
