Summary
👤
Senior🎓
Top SchoolJonathan Van Der Cruysse is a PhD candidate in Computer Science at McGill University with 11 years of software engineering and teaching experience focused on compilers, programming languages, and systems. He combines hands-on research in equality saturation and optimizing compilers with practical mentoring as a teaching assistant for core CS courses, emphasizing clear technical communication. His open-source work includes substantive backend and systems contributions to the high-profile Julia language—optimizing GC lowering and global linkage handling—demonstrating expertise in low-level runtime and performance engineering. Past industry research at Nokia Bell Labs applied compiler-style rewrites to large-scale stream processing, showing he can translate compiler techniques into distributed, high-throughput systems. Colleagues would describe him as a compiler aficionado who bridges academic rigor and production-minded systems design.
