I am a member of Center for Information Security and Trust where I conduct research within the area of digital privacy and trust; I study privacy issues among particular populations and how digital interactions affect people's sense of privacy.

My research area is human-computer interaction, with particular emphasis on privacy and ubiquitous computing. More specifically my research attempts to uncover the emergent practices and use of state-of-the-art computing technologies, such as mobile applications and social software in their native environment. I conceptualize and develop these technologies for further study, and I also study existing ones. Most recently I have looked at mobile uses of social media, leading to analyses in privacy perception by users of mobile social media.

At UCSD I was the Principal Investigator on an NSF funded project: "Transforming Social Science Virtual Organizations". I was studying the diverse intellectual practices of social science research and social scientists' use of communication technologies. These findings will be used to develop new transformative social science cyberinfrastructures. The work build on my previous work on developing and studying mobile technologies and ubiquitous computing.
