I am a Professor of 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). Riehle founded the Wiki Symposium, and more recently, the Open Symposium, now the joint international conference on open collaboration. He was also the lead architect of the first UML virtual machine. He is interested in open source and inner source software engineering, agile software development methods, complexity science and human collaboration, and software system architecture, design, and implementation. Prof. Riehle holds a Ph.D. in computer science from ETH Zürich and an M.B.A. from Stanford Graduate School of Business.
