Mathematics for Testing, Resilience and Information Security

MATRIS Science Lab

The research group MATRIS studies the mathematical foundations of complex, resilient and secure systems, and how critical infrastructure withstands hybrid threats where natural hazards and cyber attacks combine. It is a joint research lab of the University of Salzburg and FH Salzburg, led by Prof. Dimitris E. Simos.
