Systemic AI

My research interests lie in data management including (semi-)automated data curation, knowledge representation and reasoning, and natural language processing. In the past few years I have focused on developing methods and software for improving the quality, interpretability and pertinence of heterogeneous, variable and dynamic data.

I was co-investigator in the FP7 PERICLES project. I also coordinated the GALATEAS EU project and participated as an investigator in a number of European and industrial research projects related to data management, digital preservation and natural language processing.

Prior to 2008, I was a postdoc researcher at Cardiff University where I worked on representing e-learning metadata and extended the Moodle e-learning platform with corresponding ontologies. I completed my PhD in Knowledge Based Systems at Cardiff University. 

I have co-authored over 30 papers, two of which have earned best paper awards, and 10 patents and patent applications.
