My research in computational social science focuses on developing theory and methods for studying collective intelligence, crowdsourcing, and the creative industries. I promote an interdisciplinary approach to understand the behavior of connected crowds by building on techniques from network science, machine learning, statistics, and exploratory visualization.

Before joining the School of Communication I was a post-doctoral researcher at the Northwestern Institute on Complex Systems (NICO). I earned my Ph.D. in Interdisciplinary Physics from Heidelberg University, Germany in 2013. I also hold an M.Sc. and B.Sc. in Physics and Computer Science from the Babeș-Bolyai University, Romania and a B.A. in Photography, Film, and Media from the Sapientia University, Romania.

I advise graduate students in two PhD Programs: Technology and Social Behavior and Media, Technology, and Society. Prospective graduate students should apply through one of these programs.

I am always looking for outstanding undergraduates to get involved in research. Prospective undergraduate students should send me an email with their inquiry.
