$$ \Huge \textbf {Hoyun Youm} \\ \newline \small Graduate \space Student - South \space Korea $$

Hello! My name is Hoyun Youm, a Ph.D. student at the Compiler Research Laboratory (Corelab) at Yonsei University, Seoul, South Korea.

My research interests include compilers, machine learning systems, and privacy-preserving computing. I am particularly interested in hardware-aware optimization techniques for AI/ML workloads, with current work focusing on compiler infrastructures for Fully Homomorphic Encryption and encrypted machine learning systems.
