I am working on SocialLearn Project as a user experience developer. My PhD was on improving the interaction between users and the content-based image retrieval (CBIR) system from three perspectives: user interaction model, interactive interface and users.

Keys: User Interaction Model, Relevant Feedback, Interactive Interface Design, User Modelling, User Profile Analysis, Quantitative and Qualitative Data Analysis, Information Retrieval, Multimedia Information Retrieval, Social Learning.
