Welcome to my webpage at IT University. Since April 2009 I am a PhD student in the Software Development Group under the supervision of Andrzej Wąsowski.

I am working on providing tools which support developers in development and evolution of multi-language software systems. Multi-language software systems are systems which are developed using multiple GPLs and DSLs simultaneously. Currently, I am working on automatic inference of cross-language relations out of source-code bases. My research interests are in multi-language (polyglot programming), model-driven, component-based, and aspect-oriented software development.

Before starting at IT University I was working as a Junior Research Engineer at Intershop, an e-commerce platform supplier.

I studied computer sciences at Friedrich Schiller University of Jena (Germany) and graduated in 2008 as Diplom-Informatiker.

Currently, I am at Technical University of Dresden on a research visit in the Software Technology Group under Uwe Aßmann and collaborating with the spin-off DevBoost


Teaching

Want to write a Thesis?

Are you interested in writing a thesis in the fields of component-/aspect-/object-oriented software development/engineering or model-driven software development? Or in any eclipse related projects? Then check out the current proposal section or just feel free to contact me.

Current Proposals:

Formalizing and Modeling Software Development Artifacts

During software development various different artifacts are used. They range from requirement analysis documents over analysis models, source code in various languages, and documentations to configuration files. The composition of a set of such artifacts forms a software system. The software development artifacts share structural commonalities but differ also somehow. For example, a Java class is a structured document, where the structure is given by the language specification, i.e., its grammar. Similarly, an XML model is structured. What are the commonalities between those two structures? Is there also a structure for text documents? What do the structures of a text document and a Java class have in common? We are interested in research of the questions above and in related questions.

Java Model in XText

The Java model listed above is a drafty implementation of a Java5 syntax in xtext. It is drafty in a sense that it lacks any model transformations to optimize the model size. Furthermore it is a 'flat' model. That is, it does not contain references between model elements. If you are interested in references between model elements you would like to check JaMoPP or MoDisco. However, the Java model provided here allows for treating single compilation units as seperate models.
