Dr Vassil Vassilev

Prof. Vassilev graduated with an MSc in Electrical Engineering from the Technical University in Sofia and obtained a PhD in Artificial Intelligence from the Bulgarian Academy of Sciences. He was active during the nineties in both academia and industry in his home country of Bulgaria. He founded the Department of Informatics at the New Bulgarian University and led several EU funded projects dedicated to the transformation of Higher Education in Bulgaria. After a couple of years in the offshore software development business, Dr. Vassilev joined the academic community in the UK with positions at the University of Northumbria, the Open University, and London Met.

Currently Prof. Vassilev is the course leader of the Artificial Intelligence MSc at the School of Computing and Digital Media and leads several innovation projects funded by Lloyds and Innovate UK. His research interests are in hybrid intelligence and semantic technologies and their applications to cyber security. 

Prof. Vassilev is teaching Formal Specification and Software Implementation and Distributed and Internet Technologies modules to students on Computer Science BSc, and Artifical Intelligence and Semantic Technologies modules to students on the Artificial Intelligence (AI) MSc course. Additionally, he has an interest in Hybrid Intelligence and System Integration. He is also supervising several PhD students doing research in AI and it's application to cyber securty.
