Hi, I'm Hwan Heo (허환). I work where generative models, systems, and graphics meet, carrying ideas all the way from representations and training code to the meshes people actually use.

At NC AI, I lead research and engineering for the VARCO 3D team, developing production 3D AI systems across large-scale generative model training, inference optimization, and graphics algorithms. I hold both a B.S. and M.S. in Computer Science from Korea University, where I was advised by Professor Hyunwoo J. Kim. Previously, I was a Research Intern at NAVER AI Lab, mentored by Dr. Jin-Hwa Kim.

When I'm away from CUDA kernels and mesh pipelines, I'm usually playing guitar, making music, or following an unexpected STEM rabbit hole. This site is both a record of the systems I've helped ship and a notebook for the ideas I keep exploring.
