Research Summary

My research has focused on examining how the media influences public attitudes toward contested technologies and controversial environmental and health issues. One line of this research involves applying the large-scale sentiment analysis to explore social media discourse. Another line examines how the online media environment influences user attitudes and behaviors. Currently, I am interested in the effects of online interface features and message content on users' behavioral intentions.
