I am an Assistant Professor in Communication and Computer Science (by courtesy) at Northwestern University, where I direct the Technology and Social Behavior PhD program. My research lies at the intersection of computational social science, social computing, and communication. Using interdisciplinary approaches from network and data science, my research group, the Lab on Innovation, Networks, and Knowledge (LINK), investigates how networks induce biased information production, sharing, and processing on digital platforms. For example, we study the impact of networks and diversity on scholarly communication, identify expressions of collective intelligence and opportunities for innovation in crowdsourcing communities, and develop tools to support creativity and predict success in culture industries. I developed courses on network science and machine learing 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).
