Alexander Schatten

Alexander Schatten

is senior researcher at SBA Research and occasionally consultant, as well as lecturer at TU Wien.

Research Interests

Alexander is interested in sustainable and resilient management and engineering practices for complex and distributed software systems.


Bio

Alexander worked for over 10 years at the TU Wien, focusing on software engineering, complex systems and sustainable development. He published more than 40 scientific papers and more than 40 articles in technical magazines and a textbook on Best-Practice-Software-Engineering. He then gained further experience as founding CEO of a startup company and as consultant with Deloitte. Eventually he was CTO of biac/ twinformatics (IT subsidiary of Vienna Insurance Group) for three years. He now wants to resume his research career and contribute his broad expertise to establish sustainable software systems.
