PhD projects

1. Foundation of machine learning: contextual probability inspired statistical modelling - a deep learning approach, and its application e.g. digital twins.

2. Machine learning: detection learning that aims to learn signatures of objects of interest, and its applications in food authentication, virus detection, medical image analysis (disease imaging biomarker).

3. Knowledge representation and reasoning: ontological competency modelling and automated competency-based assessment.

Personal profile

Research Focus

His research interests are machine learning, knowledge representation and reasoning, and their applications in image, video, spectra and text data analyses and more recently education. He played an important role in the development of an algebraic framework for machine learning and knowledge representation, Lattice Machine; the original concept of contextual probability for probabilistic modelling, which can be used for uncertainty reasoning/quantification, probability estimation and machine learning; a generic similarity measure, neighbourhood counting, and its specialisations on multivariate data, sequences, tree and graph structures; and more recently detection learning and knowledge-based learning. He has over 300 publications in these areas. 

He is principal investigator of a number of regional, national and international projects in the areas of image/video analytics (EPSRC funded MVSE 2021-2024, Horizon 2020 funded DESIREE and ASGARD, FP7 funded SAVASA, Royal Society funded VIAD), spectral data analytics (EPSRC funded VIPIRS on virus detection 2020-2022), text analytics (INI funded DEEPFLOW, Royal Society funded BEACON), and intelligent content management (FP5 funded ICONS); and is co-investigator of several other EU funded projects. 

Prior to joining Queen’s, he was Professor of Computer Science in the School of Computing, Ulster University, in various roles including Head of the AI Research Centre, and Research Director. He is an associate editor of IEEE Transactions on Cybernetics, founding Chair of IEEE SMCS Northern Ireland Chapter (2009-2018), and a member of IEEE SMCS Board of Governors (2010-2013).
