I am a text mining specialist at NIHR Innovation Observatory, Newcastle University. I am working on information retrieval, natural language processing and machine learning to build a smart search system for clinical trials. Before that, I earned my PhD degree in computer science from the Open University, where I worked on dynamic user profiling for search personalisation.
