I am a senior researcher at the Chair of Systems Design, and experienced IT administrator (head of the IT team).
My current research is about structural properties, stability, and efficiency of complex interconnected and temporal networks.
More precisely, I study how dynamical processes evolving on a complex system are related to fundamental properties of its underlying network topology. Using data-driven modelling, I am exploring applications of these subjects to various fields ranging from Physics to Sociology and Economy.
