Biography

Michael completed a Higher Diploma in Computer Science at University College Dublin in 2000 and received his Ph.D. in Computer Science from University College Dublin in 2005. Subsequently, he was employed as a Postdoctoral Fellow in the UCD School of Computer Science and Informatics Information Hiding Laboratory and is currently a Postdoctoral Fellow in the CLARITY Center for Sensor Web Technologies.

Michael¿s research interests lie in the areas of Artificial Intelligence, Recommender Systems, Robust Collaborative Recommendation, Personalisation, Web Search and User-Generated Content Analysis. He has refereed for many Journals and International Conferences, which have included the Journal of the American Society for Information Science and Technology, User Modeling and User-Adapted Interaction, ACM Transactions on the Web and IEEE Intelligent Systems and he has served on the Program Committee of the leading International Conferences in his area of research. Michael has published 27 refereed book chapters, journal and conference papers. He is a collaborator on an Enterprise Ireland Innovation Partnership award (200K EUR funding).

Michael has also lectured in Computer Science Undergraduate and MSc. Degree Programmes at University College Dublin over several years. Previously, he has mentored the dissertations of several MSc. students to completion. Currently, he is responsible for mentoring Ph.D. and internship students.
