Office hours: by appointment

I am working as a research assistant in the project RiSE (Rigorous Systems Engineering), and was previously employed in the project FAME (Formalizing and Managing Evolution in Model Driven Engineering).

My research interests are in the areas of QBF solving and certification, formal methods in model engineering, and heuristic optimization.

I received a PhD in Computer Science (my PhD thesis) in January 2016, an MSc in Computational Intelligence (my Master thesis) in May 2010, and a BSc in Business Informatics in December 2006.

In autumn of 2013 I visited Roland Jiang's group at the National Taiwan University. I was blogging a bit about about my life there. In 2006 and 2007 I spent a year at the University of Alicante in Spain. From 2005 to 2008 I additionally worked in web and database development.

Since December 2014 I am also permanently working on our lifetime project. In my spare time I enjoy playing the violin, cooking, travelling, and learning languages, in particular Mandarin Chinese.
