PROFILE
Jonas Kastberg Hinrichsen
Worked on the mit-pdos/perennial repository to enhance the Dependent Separation Protocol (DSP) for Go channels, focusing on improving channel communication handling and protocol state management. Leveraged Go and Coq to introduce new specifications, formal proofs, and proof tooling, strengthening correctness and robustness in concurrent programming contexts. Advanced the protocol by defining abstract units for channel names and ownership, refactoring session and endpoint operations, and introducing a concurrent muxer specification with higher-order protocols. Updated examples and tooling to align with these changes, laying a foundation for safer streaming, scalable formal verification, and clearer ownership semantics in protocol design and implementation.
