My main research interests are:
1. Information retrieval : quantitative/qualitative user experience, user modeling, interactive systems and statistical analysis. I investigate users' behavior through user studies, surveys, usability tests, focus group and by studying large scale data logs. I derive patterns of users' interaction behavior. I am also interested in understanding the various forms of interaction between the systems and the end-users.
2. Machine Learning: Healthcare cost prediction models , and predicting users' personality in social network.
