## About

Ahmad Al Badawi, Ph.D. is a Senior Scientist working at the intersection of applied cryptography and machine learning. His research advances fully homomorphic encryption (FHE) toward practical, deployable systems for private AI inference.

Selected expertise: fully homomorphic encryption (BFV, BGV, CKKS, TFHE schemes), privacy-preserving machine learning, lattice cryptography, hardware acceleration (GPU and ASIC), post-quantum cryptography.

Affiliations: Ph.D. from the National University of Singapore (2018). Co-Principal Investigator and Technical Lead on the DARPA DPRIVE program (TREBUCHET team).
