Harim Chun

Decoding Cancer Complexity at Spatial & Single-Cell Resolution.

Hello, I’m Harim Chun, a Ph.D. student in Biomedical Sciences at The Catholic University of Korea and a member of PathFinderLab. I use spatial transcriptomics, scRNA-seq, and multi-omics to study tumor–immune interactions and biomarkers of therapeutic response.
