Florian Tschorsch studied computer science with a focus on computer networks as major and cultural studies as minor subject at the Heinrich Heine University Düsseldorf, Germany. From 2008 to 2010 he worked as research assistant in the computer networks and communication systems group. For the period of his master studies he was awarded a scholarship by the University of Düsseldorf and the state of North Rhine-Westphalia to encourage and support young scientists. In September 2009 and December 2010 he earned the B.Sc. and M.Sc. degree respectively. Subsequently, he joined the research group of Prof. Björn Scheuermann.
