Summary
🤩
Rockstar🎓
Top SchoolMadars Virza is a chief scientist and research-trained cryptographer with 12 years of experience bridging academic research and production-grade cryptographic systems. Formerly a Research Scientist at MIT Media Lab and a PhD in Computer Science from MIT, he co-authored and contributed performance-critical optimizations to scipr-lab’s libsnark, a widely used C++ library for zkSNARKs. Now based in Cambridge and leading research at Radius, he combines deep finite-field arithmetic and proof-system expertise with practical engineering to ship high-performance back-end components. Known for refactoring core cryptographic code and squeezing extra performance from low-level implementations, he excels at turning theoretical advances into deployable systems.
