About me

I am Reader (Associate Professor equivalent) in Data Science in the School of Engineering, Computing and Mathematical Sciences at the University of Wolverhampton in the UK. I am the head and founder of the Data Science, AI, Information Retrieval and NLP research group DAIREL. Furthermore, I am Adjunct Professor (Lehrbeauftragter) at the Bern University of Applied Sciences in Biel/Bienne, Switzerland. With a general interest in Data Science and Artificial Intelligence (AI), my focus is on human-centric Information Retrieval, generative AI and its application in disciplines such as Digital Libraries. I was general chair of ACM CIKM 2023.

Prior to this, I was Senior Lecturer in the School of Computer Science and Technology of the University of Bedfordshire in Luton, UK. I was a member of the Information Retrieval group at the School of Computing Science of the College of Science and Engineering at the University of Glasgow. Before I was working in the Information Systems Working Group at the Faculty of Engineering of the University of Duisburg-Essen, where I did my PhD on information modelling and retrieval based on user annotations. Before joining the group in Duisburg, I worked at Fraunhofer IPSI on annotation-based retrieval in Digital Humanities.

I hold a PhD from the University of Duisburg-Essen and Diploma (Diplom-Informatiker, MSc equivalent) in Computer Science from the University of Dortmund. I am a BCS Fellow as well as a Fellow of the Higher Education Academy.

I am the University of Wolverhampton's Principle Investigator of the EU Horizon Europe Marie Skłodowska Curie Staff Exchange project OMINO (Overcoming Multilevel INformation Overload). In this project, we apply information retrieval, retrieval-augmented generation and generative AI to tackle information overload. I was the University of Bedfordshire's Principal Investigator of the EU H2020 Innovative Training Network QUARTZ (Quantum Information Access and Retrieval Theory), which is concerned with formal approaches to Information Access and Retrieval based on the quantum mechanical framework. Furthermore, I have been leading and working in several national and international research and knowledge transfer projects.

Research Interests

The aim of my main lines of research is to tackle information overload (see our Nature Human Behaviour article) by supporting users in finding relevant information in large data collections more effectively. To this end, I utilise my Computer Science background and amalgamate methods from AI, Deep Learning, Information Retrieval, Information Science, NLP and Data Science. I employ cognitive and human-centric theories and combine these with mathematical modelling (e.g., quantum mechanical models), (generative) AI, machine learning and embedding models to bring the human into the loop.

In particular, I have been working on the following topics (links lead to peer-reviewed example papers):

• Chatbots and Retrieval-augmented Generation (RAG)
• Large Language Models, Authorship Attribution and Data Augmentation
• Interactive Information Retrieval inspired by Quantum Mechanics
• Probabilistic and logic-based models for Information Access and Retrieval (e.g. probabilistic Datalog)
• Interactive Information Retrieval models utilising the Principle of Polyrepresentation or Information Foraging Theory
• Bibliometric-enhanced Information Retrieval
• Annotations, Annotation Services and Information Access in Digital Humanities and Digital Libraries
• (Deep) Machine Learning and Information Retrieval
• Text Categorization and Email Categorization
• User support for Question Answering and Semantic Search on Linked Open Data
• Neural Networks and Recommender Systems
• Discussion Search and Polarity Classification
• Text Analysis and Machine Learning for Cyberstalking Detection
• Cross-cultural Information Retrieval

Please contact me if you are interested in a BSc, MSc or PhD project in these areas.
