- Security, Trust and Privacy
The research activities in this area are multifold and include formal trust and security management models in collaborative environments, applied security standards (ISO 27000 family), active defense mechanisms, attack profiling and data privacy frameworks. Novel research results have been published on the trust and security requirements for critical infrastructures and grid computing, the development of an integrated framework for active defenses and attack profiling\visualization using open-source honeypots and the design and development principles of a GDPR-compliant privacy framework.
- Middleware and Distributed Computing Systems
Research activities in this area include an extensive publication record and project participation in middleware such as status dissemination middleware and Grid computing middleware as well as in distributed systems in a variety of application domains such as medical data, active defense techniques (honeypots), cryptocurrency systems and data privacy. Prototypes of various systems in the areas above have been designed and developed, with a few being provided as open source.
- Blockchain Technologies
Research in this domain is conducted into enhancements of the blockchain technology as well as usage of the technology as a building block for proposed frameworks. Research has been done into alternative ways of rewarding miners and the related topic of how to potentially “reuse” lost values within the blockchains. Research has also been conducted where blockchain technologies have been used as one of the building blocks in proposed frameworks. The usage of the blockchain aims to enhance trust in distrusted environment and provide more openness and transparency for the involved participants. Among proposed frameworks is the “Practical e-Voting Framework”, which proposed numerous novel innovations using blockchain technologies to provide a more open and transparent election system.
- Geometric Modeling (Computer Graphics)
This research includes Geometric Modeling, Spline methods, and Subdivision methods, for modelling articulated figures based on arbitrary topological meshes. The work has been supported by a number of research grants and has been published in various International Conference Proceedings and Journals.
- Knowledge Management
The research interest in the area focuses on the successful implementation of knowledge management within a business. This involves analyzing critical success factors; examining best practices and lessons learned; investigating, developing and promoting modern technologies, etc. Special interest exists on the implementation of knowledge management in the educational sector.
- Information and Communication Technologies (ICT) in Education
Research activities in the area involve the investigation, design, and implementation of ICTs in education. Consequently, the impact of ICTs on the learning activity is also examined. Examples of ICTs examined include Web 2.0, 3.0; Social networking – communities; Online learning; Various educational applications.
