Research Interests: Weissenbacher's work centers on formal verification techniques for software and hardware systems. Key areas include:

• Hyperproperties: Analyzing properties of systems involving multiple execution traces, such as security and robustness.
• Model Checking: Applying bounded model checking to automotive software (e.g., AUTOSAR components) and concurrent systems.
• Symbolic Execution: Leveraging symbolic execution for bug detection in programs with complex behaviors like speculative execution.
• Concurrency Bugs: Formalizing heisenbugs and developing methods to extract safe thread schedules from incomplete model checking results.
• Automated Reasoning: Improving interpolation-based techniques and SAT solvers for program analysis and fault localization.

Publication Trends: His recent articles (2024-2025) emphasize symbolic execution for hyperbug detection, machine learning in security verification, and automotive software validation. Earlier works (2023-2021) explore model checking, mutation testing, and concurrent system analysis.

Projects: He leads initiatives such as:

• Abstraction-based Parameterized TLA Checker
• Bit-level Accurate Reasoning and Interpolation
• Tools for Concurrent and Distributed Systems
• LogiCs-Stipendien (Formal Methods in Computer-Aided Design)

Collaboration and Supervision: Weissenbacher co-edits conference proceedings (e.g., FMCAD 2023, CAV 2018) and supervises students in formal verification, including Andreas Fellner (model-based mutation testing), Emmanuel Pescosta (speculative non-interference), and Tobias Nießen (hyperproperty counterexamples).
