A short description of my CV can be found below.

 In 1989 I received my Master's degree with high distinction (cum laude) from the Computer Science Department of the University of Nijmegen in Nijmegen, The Netherlands. In 1993 I received my PhD in Mathematics and Computer Science from the same university. My PhD-thesis, entitled 'Information Modelling in Data Intensive Domains', dealt with the formal foundations of conceptual data modelling and conceptual process modelling. In this thesis, the conceptual modelling technique NIAM was extended with advanced conceptual modelling constructors and a formal set-theoretic foundation was given. The resulting technique was called PSM. LISA-D served as a conceptual query language for PSM and its denotational semantics was given in terms of path expressions. LISA-D exploits the natural language base of PSM and allows for an easy formulation of complex queries. Task Structures were introduced for the description of processes and they were defined in terms of Process Algebra. The research described in my PhD-thesis was carried out both at the department of information systems of the University of Nijmegen (1 day per week) and at the Software Engineering Research Centre in Utrecht, The Netherlands (4 days per week). At SERC, my research focused on meta-CASE technology in the context of the SOCRATES project and on formalization of methods and techniques in the context of the ESPRIT II project PROOFS. After receiving my PhD thesis I worked as a lecturer at the department of information systems of the University of Nijmegen for a few years. Research in this period focused on further extending the work on formal foundations of conceptual modelling. In particular, a category theory framework for conceptual data modelling was defined. This framework is both a syntactic and a semantic generalization of existing conceptual data modelling techniques. Features such as null values, uncertainty, and temporal behaviour can be added by selecting appropriate instance categories. The addition of these features usually requires a complete redesign of the formalization in traditional set-based approaches to semantics. With one of my PhD-students, Jan-Willem Hubbers, I worked on a formalization of Jakobson's Objectory in terms of Process Algebra. Teaching in this period primarily concerned the teaching of "Foundations of Information Modelling 1" and "Foundations of Information Modelling 2". These two subjects were taught to 3rd and 4th year students and dealt with the formal foundations of conceptual data and process modelling and as such comprised the results of my PhD thesis and some research done afterwards. I also supervised about a few Master thesis students in this period.

In January 1996 I started as a lecturer at the Department of Computer Science from the University of Queensland, in Brisbane, Australia . During this period I taught query optimization, distributed databases, and spatial database structures to 3rd year students and NIAM, SQL and Relational mapping to 1st years. Research dealt with the feasibility of Situational Method Engineering, the conceptual specification of workflows (in the context of the PhD-research of Alistair Barros) and the computational complexity of verification problems in workflow specifications.

As of January 1997, I have commenced my duties as a lecturer at the School of Information Systems of the Queensland University of Technology. In August 1999 I was promoted to senior lecturer (backdated to August 1998) and received the 1998 Faculty's Outstanding Performance Award for my research. In August 2000 I was appointed Associate Professor and in August 2008 I was promoted to Professor. My research activities are performed in the context of the BPM Group of which I am Co-Leader. To this day, I have around 100 refereed publications (more than 35 of these are international journal publications), among others in journals such as, Computer Journal, Information Systems, Information Systems Journal, and Acta Informatica. I have been a chief investigator in three large ARC SPIRT grants, involving Mincom, GBST, and JustWin Technologies (this grant was administered through UNSW) and I am currently involved as a chief investigator in an ARC Centre of Excellence (led by QUT's Faculty of Creative Industries), two ARC Discovery Grants (and I will be a chief investigator in another ARC Discovery Grant that will start next year), and an ARC Linkage Grant. In December 2004, Marlon Dumas and I won the ``Dean's Excellence in Research Award'' in the Faculty of Information Technology of QUT. I am an original and ongoing contributor to the Workflow Patterns Initiative and also to the YAWL Initiative, which in addition I am the leader of at QUT. I am also a co-director of BPM Center.
