Mark Wetzlinger

Curriculum Vitae

Mark Wetzlinger joined the Cyber-Physical Systems Group as a research assistant and PhD candidate under the supervision of Prof. Matthias Althoff in late 2019. He received his bachelor’s degree in Engineering Sciences in 2017 and his master’s degree in Robotics, Cognition, Intelligence in 2019. His research focuses on formal verification of continuous-time dynamical systems using reachability analysis. He is a member of the DFG Research Training Group on Continuous Verification of Cyber-Physical Systems (ConVeY). From April to September 2022, he worked with the group of Prof. Murat Arcak at the University of California, Berkeley as a visiting scholar.
