Joohyeok Kim

I am a first-year master student at the Yonsei University advised by Prof. Seong Jae Hwang at MICV (Medical Imaging and Computer Vision) Lab. My research interests are Computer Vision, Medical AI, and AI Efficiency.

This summer, I am interning at LG AI Research (Bio Intelligence Lab) on spatial transcriptomics.
