In pursuit of this goal, I am deploying rigorous reasoning methods, such as type systems and verification logics, which allow statement of the desired properties and a formal proof of their adherence. To ensure scalability, I use compositional methods, guaranteeing that individually verified parts compose to a verifiable whole. To ensure practicality, I consider verification needs arising from real-world problems. Tangible results of my research include not only formal models with correctness proofs but also software artifacts. A driving force underlying my research is the recognition that powerful and elegant solutions are fundamentally based on simple ideas, ideas that can be conveyed to and appreciated by non-experts. As such it is the aim of my research program to contribute verification tools and systems that can be used by educated practitioners, encouraging adoption of formal methods in practice.
