Top School

Chanhee Cho is a PhD student in Electrical & Computer Engineering at Purdue University with six years of hands-on experience at the intersection of computer security, formal methods, and programming languages. He contributes to rigorous, low-level verification tooling—most notably as a back-end developer on the Verus project where he implemented bit-vector operators and extended type-checking for verified Rust. His academic path spans Seoul National University and Carnegie Mellon, blending theoretical depth in mathematics and CS with applied systems work. Chanhee brings a developer’s attention to correctness, shipping tests and examples to validate language features, and prefers tackling subtle, correctness-critical engine components rather than surface tooling.

Verified Rust for low-level systems code

Role in this project:

Back-end Developer

Contributions:62 reviews, 151 commits, 47 PRs in 1 year 2 months

Contributions summary:Chanhee primarily contributed to the development of the Verus language, focusing on the bit-vector features and supporting operators. Their work involved implementing bitwise operations and extending the type system, particularly within the `sst_to_air` and `air` modules. The user made code modifications to incorporate the newly added bit-vector operators into the rust-to-vir and the type-checking process. Furthermore, they added example code and test cases to ensure proper functionality.
