Eymen Ünay
PhD Student in Compilers for Cryptography
University of Edinburgh
Hi, I am a Computer Science PhD student at the University of Edinburgh, supervised by Jackson Woodruff. I have been doing research and open-source contributions on compilers for several years.
My research focuses on Compilers for Cryptography to make them faster and more efficient. Cryptography offers emerging domains such as Blockchain, Zero-Knowledge and Fully Homomorphic Encryption (FHE) with their proof-of-concepts but lack the focus on performance. I build compilers that bridge FHE applications with performance and usability.
