Prof. Dr. Dirk Riehle is the Professor for Open Source Software at the Friedrich-Alexander University of Erlangen-Nürnberg. Before joining academia, Riehle led the Open Source Research Group at SAP Labs, LLC, in Palo Alto, California (Silicon Valley). Before this, he was the co-founder of an on-demand business software startup in Berlin, Germany, which used agile methods and strategically employed open source software. Riehle works on open source and inner source software engineering, agile methods and continuous delivery, complexity science and human collaboration, and software design. Prof. Riehle holds a Ph.D. in computer science from ETH Zürich and an M.B.A. from Stanford Business School. He welcomes email at email@example.com, blogs at https://dirkriehle.com, and tweets as @dirkriehle.
In more detail: Riehle’s dissertation at ETH Zurich on object-oriented frameworks and design patterns explored the use of collaboration-based design (then called role modeling) to reduce complexity in the engineering of object-oriented software systems. It emphasized the use of design patterns in framework design and construction. He also translated the seminal Design Patterns book into German, all while employed at UBS’ Ubilab, a Zurich-based industrial research lab, during the late 1990s. From 1999 to 2002, Riehle lead the design and implementation of the first UML virtual machine while employed at Skyva, a Boston-based software startup. The UML VM interpreted UML models as programs and made it faster, better, and cheaper to develop business applications. UML was treated as a framework for domain-specific languages for different aspects of business modeling. Skyva was acquired by ABB. After receiving an M.B.A. from Stanford Business School, Riehle co-founded a software startup in Berlin, Germany that provided on-demand software (SaaS) to small businesses. In 2006, he moved back to the United States to work for SAP in the Silicon Valley, where he was the principal investigator of open source and Web 2.0 applications research. In 2009 he moved to Germany for his current position as a professor at the University of Erlangen.
Riehle has published in leading journals and conferences, including the CACM, Computer, IEEE Software, IEEE TSE, ICSE, and OOPSLA. His publication record comprises more than 50 peer-reviewed and well-cited academic papers. He is serving on the editorial boards of TPLoP, IJOSSP and IJODE and he has been a reviewer for many leading journals, transactions, and conferences on object orientation and software engineering, including ACM TOSEM, IEEE TSE, OOPSLA, ECOOP, and OSS. He is the founder and chairman of the steering committee of the International Symposium on Open Collaboration conference series and a founding member of the steering committee of the Onward! conference series. He is a member emeritus of the board and prior treasurer of the Hillside Group, the U.S.-based non-profit behind the software patterns community. He is a frequent speaker at academic conferences and colloquia and industry events alike.
