Mag.rer.soc.oec. Dr.rer.soc.oec.

I studied Business Informatics at Vienna University of Technology where I received my master’s degree and my PhD. From 2006 until the end of 2007 I worked as a researcher at the Research Studios Austria. In 2008 I joined the Business Informatics Group’s team to work on various research projects including BSopt (Business Semantics on top of Process Technology) and ERPEL (E-Business Registry Permitting Enterprise Liaisons).

My research focuses on aspects of inter-organizational communication such as Electronic Data Interchange (EDI), inter-organizational business process modeling, business document modeling, and service-oriented architectures. Currently, I am working on topics related to the computerization of manufacturing and retail – in particular in regard to procurement and distribution automation.

Furthermore, I am interested in Web application development and its related technologies.

In 2011 I joined the team of ecosio GmbH, a company providing EDI solutions for companies of any size. Nevertheless, you may still find me at the university from time to time, holding lectures for the Business Informatics Group.

Public Private Interoperability

by Philipp Liegl, Christian Huemer, Christian Pichler

The research studio Public Private Interoperability (PPI) develops methods and tools targeting the inter-organizational integration of enterprises and organizations of the public sector. Service-oriented architectures and their implementation by Web Services are the current state-of-the-art technologies for this kind of integration problems.

E-business Registry Permitting Enterprise Liaisons

by Mario Topf, Philipp Liegl, Dieter Mayrhofer, Christian Huemer

The project ERPEL targets at an e-business registry serving as a backbone for executing on-the-fly e-business transactions between semantically enabled ERP systems. By on-the-fly e-business transactions we understand transactions that are conducted between companies, which are not yet in a partnership and dynamically find each other in order to engage in e-business transactions.

Business Semantics on top of Process Technology

by Mario Topf, Philipp Liegl, Tanja Mayerhofer, Christian Huemer

The BSopt project will deliver an integrated methodology for inter-organizational systems spanning from business models over business process models to their execution in a service-oriented architecture (SOA). Integrating business processes into a SOA is certainly a hot topic.
