Researcher

Alexander Günther

Alexander Günther is a researcher who studies risk assessment for machine-learning components in safety-critical systems. He earned a BSc in Mathematics at TU Kaiserslautern in 2019 and an MSc in Mathematics there in 2022. At RPTU, he began a PhD in Informatics in 2022 and earned a BSc in Informatics in 2023. His work produced methods for failure-on-demand analysis, confidence-aware fault trees, dependent-data classification, Markov-chain analysis, and normal-classifier risk from 2023 to 2026. As of October 2026, he is a PhD student and research assistant at RPTU's Software Engineering: Dependability chair.

Timeline

  1. 2015–2023

    Mathematics and informatics degrees

    He studies mathematics at TU Kaiserslautern from 2015 to 2022, earning a BSc in Mathematics in 2019 and an MSc in Mathematics in 2022. At RPTU, he begins a PhD in Informatics in 2022 and earns a BSc in Informatics in 2023.

  2. 2023

    Failure-on-demand analysis

    In 2023, he presents a method for score-based binary classifiers that estimates a single reliable failure-on-demand value for system safety analysis.

  3. 2024

    Confidence-aware fault trees

    At ARES 2024, he, Sebastian Vollmer, and Peter Liggesmeyer present Confidence-Aware Fault Trees. Their method adds confidence levels to fault-tree analysis and uses failure-rate bounds for basic events that hold at a stated probability.

  4. 2025

    Risk estimates for dependent data

    In 2025, he coauthors Single-Valued Risk Estimation in Classification for Dependent Data with Sebastian Vollmer and Peter Liggesmeyer for IEEE AITest.

  5. 2025

    Markov chains for ML systems

    In 2025, he coauthors Continuous-time Markov Chains and their Limit Distribution for Systems with Machine Learning Components with Joscha Carra, Paul Schädrich, and Peter Liggesmeyer.

  6. 2026

    A bound for normal classifiers

    At ESREL 2026, he and Peter Liggesmeyer publish Single-Valued Risk Bound for Normal Classifiers.

  7. As of October 2026

    PhD student and research assistant

    As of October 2026, he is a PhD student and research assistant at RPTU's Software Engineering: Dependability chair. His research focuses on risk assessment for machine-learning components in safety-critical systems.
