Nik Bessis

Nik Bessis is currently a principal lecturer (Associate Professor) in the Department of Computer Science and Technology at University of Bedfordshire (UK). He obtained a BA (1991) from the TEI of Athens and completed his MA (1995) and PhD (2002) at De Montfort University (Leicester, UK). His research interest is the analysis, research, and delivery of user-led developments with regard to trust, data integration, annotation, and data push methods and services in distributed environments. These have a particular focus on the study and use of next generation and grid technologies methods for the benefit of various virtual organizational settings. He is involved in and leading a number of funded research and commercial projects in these areas. Dr. Bessis has published numerous papers and articles in international conferences and journals, and he is the editor of two books and the Editor-in-Chief of the International Journal of Distributed Systems and Technologies (IJDST). In addition, Dr. Bessis is a regular reviewer of several journals and conferences and has served as an associate editor, a scientific program committee member, and a session chair in numerous international conferences.
