Computational Analysis of Biomolecular Data for Medical Applications from Bulk to Single-cell Kaiyi Zhu High-throughput technologies have continuously driven the generation of different biomolecular data, including the genomics, epigenomics, transcriptomics, and other omics data in the last two decades. The developments and advances have revolutionized medical research. In this dissertation, a collection of computational analyses and tools, based on different types of biomolecular data with
