Recommender Systems is one of our core research areas, here at Trinity College Dublin in Ireland. We particularly focus on the evaluation of recommender systems, the development of real-world recommender systems, recommender-system APIs and recommender-systems as-a-service, user modelling, and several aspects more (e.g. labelling of recommendations, impact of demographics, recommendation persistence, position bias, choice overload, and recommender system datasets). For more details on our work on recommender systems read the blog posts below, have a look at the menu above, or visit us at Trinity College Dublin, Ireland. I am also open to industry collaborations and my group often has open positions for PhDs in recommender-systems and machine learning. You find our main website at http://recommender-systems.ie and the current page at http://dublin.recommender-systems.ie.
