## Contributions
André Platzer is best known for his work on differential dynamic logic (dL), a formal framework for verifying the safety and correctness of cyber-physical systems. His research has led to the development of KeYmaera, a theorem prover for hybrid systems, which has been widely adopted in both academia and industry. Platzer's work bridges the gap between continuous and discrete systems, enabling rigorous analysis of systems that combine physical processes with computational control.

His publications include foundational papers on the logical analysis of hybrid systems, and his book *Logical Foundations of Cyber-Physical Systems* (2018) is a key reference in the field. Platzer has also supervised doctoral students, including Sarah Loos and Nathan Fulton, further extending his influence in formal methods research.

## FAQs
