Personal Information

Tobias works on understanding how we operate networked systems, and how the way we operate them impacts security. For that, he combines classical network measurement with methods from the field of human factors. He got his PhD in 2017, and joined the MPI after being a (permanent position) assistant professor at TU Delft from 2017 to 2022.
