Member of the Software Architecture Group (Hasso-Plattner Institut, Germany).
Former member of Distributed Systems Group (Trinity College Dublin, Ireland) and Software Composition Group (University of Bern, Switzerland).

My research interests include languages and tools to support component-oriented and aspect-oriented software development. For details concerning my research, check out the publications page. On Google Scholar. On DBLP. List of citations.

I won the Ernst-Denert Prize 2006 for Software Engineering for my work on Classboxes. The ceremony was held in Dresden (Germany) on October 4th 2006. Pictures are available.

Research question:

I am interested in the widest sense of software evolution and programming languages. The research questions I have been investigating since I started my Ph.D. are Can a software evolve?, How programming languages affect software evolution? I am currently investigating why and how systems perpetually evolve. The systems I am currently formulating hypotheses for are based on modules systems, component model, aspects-oriented languages and embedded devices.

Research activities:

• Realtalk -- An object-oriented programming languages for small embedded devices such as wireless sensor networks.
• Classboxes -- A module system to support class extension. It allows changes to be applied to a system in a non-invasive way by using scopes.
• Traits -- An object-oriented composition mechanism for building classes from behavioral building blocks. Traits is an alternative to multiple inheritance.
• FacetS -- An open aspect mechanism where aspects can be dynamically created/installed/removed and semantics elements are first class entities.

Keywords:

Software Engineering, Object-Oriented Programming, Language Design, Aspects-Oriented Programming, Reflection, Modules, Teaching OO, Security, Mixins, Traits, Classboxes, Scheme, Smalltalk, Java, Ruby, C#, Embedded systems and Automotive.
