Overview
I am a Lecturer in Computer Science and Informatics at the Cardiff University, UK. I teach both undergraduate and postgraduate modules. My main areas of research lies in Semantic Web, Knowledge Representation and Reuse. Presently, my research work focuses on developing strategies for using large language models (LLMs) explictly and implicitly for multiple concept embeddings.
I have also been an active participant in other projects with the KnowDive Group, University of Trento.
My Ph.D was in Ontology Modelling - a formal ontology for facet discovery and knowledge representation. I proposed a method to build core ontology comprising a small set of concepts, it would save a lot of time and expense of the domain developers interested in building application ontologies.

Research
My research interest lies in knowledge representation and reuse. Knowledge needs systematic and scientific representation for efficient organization, interpretation and reuse.
Currently, I am working on three different research projects.
- Explore Large Language Models (LLMs) such as ChatGPT and GPT-4 for knowledge extraction.
- Learn concept representations, investigate multiple concept embeddings for imporving multi-label classification.
- Build a comprehensive and easily accessible global farm-to-fork ontology about food and agriculture.
Teaching
I am module leader for the following modules:
- CMT313 Software Engineering, which is a dual semester module taught in MSc Computing programme.
- CM6125/CM6625 Database Systems, which is a spring semester module taught in 1st Year of the Applied Software Engineering programme.
I am also a Year Tutor for 2nd Year Applied Software Engineering (ASE).
