January 2005-Now, Assistant Professor, University of Twente
Department of Computer Science, Enschede, The Netherlands.
Leading the Software Architecture Design group including three PhD students and one Postdoc. More information can be found on the Trese-Synthesis site. Two positions are carried out in the Television Related Architecture Design for Reliability (Trader project) primarily coordinated by Embedded Systems Institute. The third position is carried out in the European Network of Excellence on Aspect-Oriented Software Development project, where we are one of the main coordinators in the Analysis and Design Lab. Finally, the fourth position is carried out in the context of the Jacquard program funded by the Netherlands Organization for Scientific Research (NWO). Hereby we focus on identifying and specifying so-called aspects at the software architecture design level.

September 2002-July 2003, Assistant Professor, Bilkent University
Visiting assistant professor at Bilkent University, Department of Computer Engineering, Ankara, Turkey
Visiting assistant professor at Bilkent University, Department of Computer Engineering in Ankara, Turkey. I have taught  courses on object-oriented programming, software architecture design and aspect-oriented software development. In addition have continued my research on synthesis-based software architecture design, aspect-oriented software architecture design and design space modeling.  

October 1999 - October 2002: Post-Doc
Dept. of Computer Science, University of Twente
This was financed by the Dutch Science Organization (NWO). My basic research activities involved design space synthesis, design alternative analysis, design alternative evaluation based on quality factors and fuzzy-reasoning based heuristic rule modeling. We formalized the heuristic rules of object-oriented methods and applied fuzzy reasoning techniques.

September 1995-March 2000: PhD Student
Software Engineering, Dept. of Computer Science, University of Twente.
My PhD research activities were carried out in the industrial context of Siemens-Nixdorf for designing adaptable car dealer software architectures. In particular the first three years we had regular (monthly) meetings with the researchers and engineers at Siemens-Nixdorff, which provided me important insights in the industrial domain. I did research on the notion of software engineering, problem solving, software architecture design methods, quality modeling in software design and design space modeling. My research resulted in the Synthesis-Based Software Architecture Design Method (Synbad) which we applied to design an adaptable transaction system architecture for the car dealer management system of Siemens-Nixdorff. Synbad can be considered as the first software architecture design method that explicitly implements the concept of synthesis. 

March 1994-September 1995: Research Associate  
Dept. of Computer Science & Dept. of Education, University of Twente
Directly after I finished my graduation thesis I started as a researcher in a joint project between Dept. of Computer Science and Dept. of Education at the University of Twente. Hereby, I did research on object-oriented modeling, design and its application to the design of intelligent tutoring systems. This research resulted in several conference papers and a technical report on the design of a reflective tutoring system shell from which customized tutoring systems can be derived. 

Sept. 1988-Mar. 1994, University Education
From September 1988 till September 1989 I have studied Electrical Engineering at the University of Twente. Later I switched to Computer Science, which aligned better with my personal preferences and received my M.Sc. degree for Computer Science  in the TRESE-group in March, 1994. During my graduation assignment I have designed and implemented (in Smalltalk) an object-oriented framework for atomic transactions in a dynamic and configurable environment. The framework included  run-time adaptation of transaction protocols and with this framework over ten different run-time adaptable transaction systems were produced for different requirements of a distributed system.

Dec. 1993 - Mar. 1994, Internship AT&T
AT&T, Huizen, The Netherlands.
At this time object-oriented was getting popular in industry and I worked in a pilot project for assessing the value of object-oriented software development. At AT&T I designed and implemented (in C++) an object-oriented framework for user-interfaces that was later really used for complaint and fault registration of internal projects. My internship report included around 90 pages.

Pre-University College Education, Isala College, Sep. 1982-Sep.1988
I followed my pre-university education ('Atheneum') at the Isala College, Silvolde, The Netherlands. My eight (seven was regular) examination subjects were: Dutch, English, French, German, Theoretical Mathematics, Applied Mathematics, Physics, Chemistry.

1976-1982, Primary School
We have immigrated to The Netherlands in 1974. After two years of nursery school I started at the primary school 'De Dobbelsteen', in 1976. For the national examination (CITO) I scored for mathematics 100 (over 100).
