Alexander Viehl studied computer science at the University of Karlsruhe, now the Karlsruhe Institute of Technology (KIT), from 1999 to 2004.
His studies focused on the architecture and cryptographic security of software systems and the design and architecture of embedded systems and microprocessors. He also dealt with medical technology.
Alexander holds a Ph.D. in Computer Science from the University of Tübingen.

He has been a research assistant since October 2004, project manager since August 2007 and head of department at the FZI Research Center for Information Technology in the Department of System Design in Microelectronics (SiM) since April 2012.

Since July 2016, Alexander Viehl has headed the Intelligent Systems and Production Engineering (ISPE) department at the FZI and coordinates mobility research at the FZI.

His work focuses on model-driven design methodology for safety-critical embedded hardware/software systems, verification and validation of technical systems, optimization methods for software-intensive AI systems, virtual prototyping of cyber-physical systems, energy-efficient and safe assistance systems, and AI's use for mobility systems.
