“You gotta make your own kind of music
Sing your own special song”

(Mama Cass Elliot)

My research goals are to explore and develop computational models and techniques to help users better access and retrieve more relevant information while doing their jobs more efficiently and effectively. To achieve my research goals, I have focused on inter-disciplinary research in three main areas, specifically: user modeling, information retrieval and human factors. The fundamental idea behind my research is to capture information dynamically about a user and use it to improve retrieval performance and user performance. In my approach, I combine the system-centered approaches and user-centered approaches by taking a well-established evaluation framework in information retrieval while exploiting the strengths of formal knowledge representations in artificial intelligence for building the model.In addition to the main research stream, I am also interested in computer supported cooperative work (CSCW), human computer interactions (HCI), human factors (HF) and distributed computing (DC). Below is the list of my papers classified into several main research topics and the summary of my dissertation.
