My research

My interests lies in social-economic perspectives of the digital age and how they affect individuals and society. My research takes two paths. The first focuses on implications of the behavior of individual contributors to social-computing systems on the performance of these platforms. The second studies economics of information and the behavior of consumers of information goods. Recently I am engaged in studying the development of ideas and knowledge by applying computational methods to large corpora of text.
