Research ENVIRONMENT
Since november 2008, I am working as an assistant professor in the IS lab at the TU/e. Here, I am part of the BPM and healthcare research clusters. I am supervising several bachelor and master theses related to MDE/BPM applications for healthcare. If you are a talented student with motivation to contribute to this research, please do not hesitate to contact me.
Research FOCUS
Within the horizontal BPM cluster, I am the specialist on process model transformations based on graph transformation tools and techniques. Within the vertical healthcare cluster, I am the specialist on automatic care path abstraction.

I focus on the BPM area, because it is one of the common strengths of the IS group members. I focus on the healthcare domain, because I feel responsible to contribute to that increasingly budget-controlled domain, where ad-hoc processes are still prevalent.

Research EVOLUTION
In september 2002, I started my research as a grant student within LORE, under the supervision of Prof. Dr. Serge Demeyer. Between 2003 and 2008, I have worked as a research assistant within FOTS, under the supervision of Prof. Dr. Dirk Janssens. I have coordinated the development of the MoTMoT tool, which has served as a vehicle for the group's model transformation research. On April 4, 2008, I have obtained my doctoral degree from the University of Antwerp. As a post-doctoral researcher, I have applied my modeling and model transformation expertise in a project related to MP-SoC applications. In november 2008, I have introduced my model transformation research to my new IS lab members. In the meanwhile, I am collaborating with two collegues (Eshuis and Dijkman) on these topics and I aim to spread my MDE enthusiasm within the IS group in order to make our group internationally recognized in this field.
Research TOOLS
As the organizer of the transformation tool contest, I have also developed a platform for supporting Reproducible Research: see SHARE (documentation, screencast). In a nutshell, SHARE enables you to share an optimally configured (virtual) machine to fellow researchers. SHARE is used by other workshops than the transformation tool contest too. Please don't hesitate to contact me if you like to apply SHARE for your own workshop/conference/journal too.

Together with Marco Comuzzi, I have recently demonstrated how SHARE's virtualization principles could disrupt the healthcare industry too! A paper that discusses our proof-of-concept has been submitted for conference publication and we are already working on a more elaborate follow-up article... to be continued!

Ph. D. Research log in Model Driven Engineering (MDE)

Model-driven Development of Model Transformations

I have investigated ways to model model management tools in the context of the Model Driven Engineering paradigm. I have focused on model refactoring, model synthesis and model synchronization.

As you can see from my publication list, I have focused on domain model refactorings in 2002-2003. First of all, I have contributed to a research roadmap of refactoring. Next, I have evaluated (and subsequently extended) the UML metamodel, I have used OCL to automate the refactoring process (by means of formal refactoring contracts) and I have investigated how Fujaba could be used to generate refactoring code from visual model transformation specifications. In 2003-2004, we made our approach applicable in any UML compliant tool by designing a UML profile for Story Diagrams and developing an open source compiler towards JMI standard compliant repository manipulation code.

After I had identified the need for more declarative transformation modeling language constructs in a series of model synthesis case studies, I have contributed a <<copy>> operator to the graph/model transformation community. The operator is made executable (and understandable) using a higher order transformation. The higher order transformation is modeled using plain Story Diagrams. Remark that I still do not consider the extended version of Story Diagrams the ultimate language for modeling transformations (e.g., we need at least a <<merge>> operator and non-deterministic matching too). However, I do consider the language architecture proposed in my thesis and SLE paper (UML profile + Higher Order Transformations) the way to contribute new transformation language operators. In contrast to related work, the proposed approach clearly separates and reuses mainstream graph transformation infrastructure and minimizes tool lock-in.

For a gentle introduction to the approach, please check out the recording of my Ph.D. presentation for the general public:
