In the fall of 2016 I moved to the IT University of Copenhagen to take up an Associate Professorship in User Experience and HCI. My research focuses on user experiences around location-based applications and social media, and combines studies of social media practices with interaction around location-sensor technologies, in order to provide better knowledge of how to design ubiquitous computing technologies for everyday practices.

During 2015 and 2016, I was a visiting professor at Cornell Tech. I was working with colleagues in the Connective Media group where I also taught a graduate course on research methods. I am still collaborating with researchers on projects related to location-based connective technologies for urban social practices such as urban navigation as well as anonymous social media practices.

Between 2012 and 2016 I was an associate professor at Stockholm University, the Department of Computer and System Sciences where I was also the head of the ACT research unit. I was running the LX Lab bringing together researchers and students who are interested in location-based media and location-based experiences, for example for interactive drama and urban exploration.

At UCSD (2007-2011) 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. We recently developed TagPad, a tool for interviewing participants and analyzing social science studies.

My research area is human-computer interaction, with particular emphasis on 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.

Ubiquitous computing technologies are challenging to evaluate, and I therefore use a variety of methods to study technology use in-situ, constantly reevaluating the techniques to better fit the evaluation at hand. I employ qualitative methods such as ethnography and interview methods and often supplement analysis with log-analysis and experimental methods.
