Research Interests
I’m interested in Programming Languages and Verification, Interactive Theorem Proving, Language Design, Compilers, Specifications, and Software Engineering.
Currently, I’m working on a verified compiler from a very simple C-like language to RISC-V machine code. This compiler connects to a program logic framework developed by my colleague Andres Erbsen, and to a verified RISC-V processor developed by my colleague Joonwon Choi. Together, we’re working on an end-to-end theorem which states that if we use the program logic to prove that a program satisfies an IO specification, and use the compiler to compile it and then run it on the processor, the processor satisfies the same IO specification. The source code of this project is on GitHub. We don’t have a paper about it yet, but I gave a presentation focusing on the RISC-V part of the project at the RISC-V Summit 2019, and you can find the video recording here.
Past Projects
- I was visiting Dr. Toby Murray at the University of Melbourne for 10 weeks to work on information flow control proofs for C
- For a six months master thesis internship, I was working with Prof. Andrew Appel’s group at Princeton, improving the proof automation tactics of their Verified Software Toolchain, and using it to verify the AES encryption implementation of mbed TLS
- During my master’s at EPFL, I was working with Prof. Martin Odersky’s Scala lab on the Dependent Object Types project, a formalization of the core of Scala’s type system, writing proofs on paper and using the proof assistants Twelf and Coq
- For a class project at EPFL, I contributed to the function termination checker of Leon, a tool for verification and synthesis of Scala programs by Prof. Viktor Kuncak’s group
- While working at the Scala lab, I contributed to dotty, a new Scala compiler serving as a research platform to investigate new language concepts and compiler technologies for Scala
- For my bachelor thesis, I designed, explored and implemented a simple structurally typed language in PLT redex
