Stefan Brunthaler

Stefan Brunthaler

is key researcher at SBA Research and professor at Paderborn University.

Research Interests

His research focuses on software systems: He builds new systems that solve challenging and important problems in the intersection of computer security and programming language implementation. Specifically, he has been working in language-based security, focusing on automated software diversity, and information-flow tracking for JavaScript. Stefan also has extensive experience in implementing and optimizing dynamic programming languages — in particular Python: his most recent advances lead to performance improvements of up to more than five-fold when compared to standard Python. Recently, Stefan has been making inroads towards verifying semantic preservation of his interpreter optimizations using Coq.


In February 2011, Stefan received a Dr. techn. degree in computer science from the TU Wien under the supervision of Prof. Jens Knoop. He has been a postdoc at the research group of Prof. Michael Franz from April 2011 until June 2015. As a postdoc at the University of California, Irvine, Stefan supervised 15 graduate students (five of which graduated with PhD in 2014 and 2015), published more than 20 papers, submitted four patent applications to the USPTO, taught a class (ICS45J) as the instructor of record, and was instrumental in acquiring more than four million US dollars in highly competitive grants from DARPA and NSF.
