After finishing my computer science studies with a German diploma (about the same as Master), I stayed at the university for another four years and worked as a researcher at Computer Networks Group at Technische Universität Dresden. After working on a framework for developing mobile applications I switched to a cooperation project with Citrix about a large-scale testing platform enabling combined network, functional and load tests. During my time at the university, I did my PhD, published some papers, advised students with their theses and gave lectures on multi media communications.


In 2015 I got my PhD for my work on using “Network Emulation for Large-Scale Tests of IP-based Audio / Video Communication Systems”. A year later I won the innovation price of industry club of saxony and TU Dresden for applying the thesis’ results in an industry context.
