Hi, I'm Jun Zhang — a PhD at China Pharmaceutical University (CPU). I work on NGS (Next-Generation Sequencing) data analysis and build bioinformatics tools, mostly in R and Python, with some Julia and a lot of Linux.
My research focuses on epigenetics and sequencing data analysis: ATAC-seq, ChIP-seq, MeRIP-seq and Ribo-seq, studying how gene expression is regulated from chromatin accessibility to RNA modifications and translation. I enjoy connecting wet-lab insight with computational tools to dig deeper into biological questions.
