I am an Assistant Professor in the Department of Communication Studies at Northwestern University and (by courtesy) the Computer Science Department of the McCormick School of Engineering. My research in computational social science aims to understand and support collective intelligence and science communication online. Using interdisciplinary approaches from network and data science, my research group, the Lab on Innovation, Networks, and Knowledge (LINK), investigates the impact of network embeddedness and diversity on scholarly communication, identifies expressions of collective intelligence and opportunities for innovation in crowdsourcing communities, and develops tools to support creativity and predict success in culture industries. I developed and teach the 'Cultural Analytics' course to train students for careers at the intersection of creative occupations and data science. My research and teaching have been recognized with an NSF CAREER and CRII Award. I received my PhD in Physics from the University of Heidelberg, Germany. Prior to becoming a faculty member at Northwestern, I was a postdoctoral fellow at the Northwestern Institute on Complex Systems (NICO).
