I am Research Fellow at the Mannheim Centre for European Social Research (MZES) with a special focus on online and offline political participation, political communication, digital media, social capital and social network analysis. In 2011-2013 I was Alexander von Humboldt postdoctoral fellow at the MZES, University of Mannheim, where I currently conduct research on (online) civic and political engagement, and teach political communication and internet politics. As of February 2016 I am also invited lecturer at the Hertie School of Governance in Berlin, where I teach a course on theories and methods in new media political communication, at the School’s Master of Public Policy.

My new book is now available in Kindle and Hardcover version and can be purchased on Amazon. You can also have a look at some of the content at Google Books.
