About
Overview
I'm the University College Dublin Ad Astra Fellow at the School of Information and Communication Studies and Senior Lecturer in Media and Communication in the Department of Media, Culture and Creative Industries at City, University of London. Previous to that I held research positions at the University of Sao Paulo, University of California at Davis, and Duke University, where I am an affiliate of the Duke Network Analysis Center.
My work addresses sociological aspects of digital media with a substantive interest in the cross-effects between online and offline social networks. My research brings together communication and computational social science and the source code of my projects is available on CRAN and GitHub.
