Senior Cryptographer - Homomorphic Encryption
I work in privacy-preserving computing as a research scientist and cryptography software engineer, conducting both research and engineering in fully homomorphic encryption, SNARKs, and STARKs since 2019. My experience spans academic research and industry, where I have designed and deployed privacy-preserving machine learning and analytics systems for large-scale B2B applications. In late 2025, I founded Ideal Rings Lab, an FHE engineering and advisory firm, while continuing to lead research and development at Phantom Zone.
I am a co-author and principal contributor of Lattigo, one of the most widely adopted open-source homomorphic encryption libraries. More recently, I authored Poulpy, the first FHE library to adopt bivariate polynomial representations for torus polynomials. For consulting, audits, and applied FHE engineering services, see Ideal Rings Lab.
Ideal Rings Lab is the FHE engineering and advisory firm founded by Jean-Philippe Bossuat.
It focuses on helping teams:
- assess whether FHE is the right fit for a concrete use case
- review existing FHE projects and codebases
- add senior engineering expertise to ongoing privacy-preserving systems work
If you are looking for consulting, project audits, or hands-on FHE engineering, visit Ideal Rings Lab, Jean-Philippe Bossuat’s FHE engineering and advisory practice.
Phantom Zone is a research organization dedicated to privacy preserving computation.
We focus our work on:
- Fully Homomorphic Encryption (FHE)
- (zk)-SNARKs/STARKs
- Program Obfuscation
Our current projects include:
- Poulpy: a general-purpose Rust FHE library over the Torus $\mathbb{Z}_{N}[X]$, based on bivariate representations $P(X, Y)$.
- Phantom: a RISC-V32 encrypted virtual machine.
