Laura Mahrenbach has been working as a post-doctoral researcher at the Professorship of Computational Social Sciences and Big Data at the HfP/TUM since January 2017. Prior to this position, she worked as a post-doc at the Technical University of Dresden, an assistant professor at Curry College, a research associate at the Ruhr-University Bochum and a graduate assistant at Florida State University. She completed her Ph.D. at the Ruhr-University in 2011.

Laura’s research interests include emerging powers (especiall Brazil, India and China), global economic governance, big data and digitalization. How can we understand and explain these states’ changing role in global affairs and institutions? What are the implications for established powers, such as the United States? What role(s) do big data and digitalization play in their rise? And how can big data facilitate or hinder national development and international leadership aspirations?
