PROFILE
Eric Crockett
During a two-month period, Evan Crockett enhanced the google/heir repository by developing advanced features for homomorphic encryption and compiler infrastructure. He introduced a dedicated CKKS dialect operation for relinearization and key-switching, replacing previous polynomial-based approaches to improve runtime efficiency and code clarity. Evan also added coefficient extraction and input verification operations to strengthen cryptographic integrity. In the following month, he expanded the MLIR polynomial dialect with NTT/INTT support and modernized operation creation APIs, while cleaning up Bazel build configurations to reduce noise. His work demonstrated depth in C++, MLIR, and compiler design, focusing on maintainability and robust cryptographic workflows.

Feb 1, 2026February 2026: Focused on core expressiveness and maintainability improvements for google/heir. Delivered MLIR polynomial dialect enhancements with NTT/INTT support and polyattr forms; cleaned Bazel build configuration to reduce noise from external/auto-generated code; modernized API usage by standardizing operation creation to Op::create(builder, ...). No major bugs fixed this month. Impact: richer polynomial representations, clearer builds, and improved code readability and maintainability.

Jan 1, 2026Month 2026-01: Delivered CKKS Dialect: Key-switching and Relinearization Enhancements in google/heir. Replaced the previous approach of lowering RelinearizationOp to Polynomial with a dedicated CKKS dialect operation, boosting runtime efficiency and code clarity for key-switching and relinearization. Added coefficient extraction and input verification operations to strengthen cryptographic integrity. Implemented KeySwitchInner decomposition with new utilities to support decomposition, leading to cleaner, more maintainable code and easier future enhancements. This work reduces complexity in cryptographic paths and enables more reliable performance for homomorphic encryption workloads, setting the stage for further optimizations.
