Staff Profile

Hello, welcome to my information section! 

I’m currently working as a Senior Lecturer of the Scalable Computing Research Group. Before joining Newcastle University, I worked as a lecturer of the Department of Computer Science of University of Reading, research fellow at LIP6, Pierre et Marie Curie University and French National Center for Scientific Research (CNRS), Department of Computing and Information Systems of University of Melbourne, and Research School of Computer Science. I did my Ph.D study in Web Intelligence and Data Mining Group, QUT, Australia. I am a Fellow of The Higher Education Academy (HEA), UK. 

My research interests include: Data Mining, Machine Learning, Natural Language Processing, Recommender Systems, Personalisation. You can find more detailed information from my personal website. 

My current research lies in the areas of Data Science and Artificial Intelligence (Natural Language Processing). I try to answer these questions:

1) How to make better recommendations in the era of Big Data? For example, explainable Recommender Systems, conversational Recommender Systems, trust-worthy Recommender Systems.

2) How to discover new knowledge based on complex, large-scale, noisy, diverse, and dynamic data? For example, social data (e.g., social media posts in Twitter), pervasive data (e.g., exercises data in smart phones), text data, image data, environment data, graph-structured data.

3) What is intelligence and how to model, test, and apply findings and theories of biological learning to machines?

• Available PhD Student Projects

User Profiling for Personalisation. This project is to develop scalable and effective explicit and implicit user profiling approaches to discover new knowledge about users’ individual interests, preferences, emotional status, and information needs. It will use advanced natural language understanding, Large Language Models, generative models, reinforcement learning, and deep learning techniques to construct user profiles based on both explicit and implicit multi-modality (images, text, audio, graph, temporal data) user behaviour data. The proposed user profiling techniques will be applied to recommender systems to make personalised recommendations.

Hashing Techniques for High Dimensional Data. Hashing is a key technique to analyse big data. It has been popularly used for dimensionality reduction and data size reduction. This project is to develop novel hashing algorithms to sample, compress, and index big data such as multi-modality data (images, text, audio, graph, temporal data) to facilitate effective and efficient information retrieval and recommendation. This project will also explore machine learning based hashing techniques. This project will contribute to new solutions to make better usage and processing of big data.

Other directions such as Responsible Recommender Systems (e.g., trustworthy, safe), Conversational Recommender Systems, Dialogue agents for mental health, Scalable Recommender Systems are also available. Note: Good programming skills and theoretical modelling are required for all projects.
