Research
Overview
Dr. Kevin Johnson is a Research Scientist in Professor Roel Verhaak's laboratory with a strong background in cancer genomics, epigenetics, and glioma evolution. In the Verhaak Lab, he leads computational analyses of multi-modal bulk and single cell longitudinal genomic data to better understand glioma treatment resistance. Dr. Johnson has a proven track record of producing high-quality research including first or co-first author publications in scientific journals such as Nature, Nature Genetics, and Nature Communications. He is also an active research member in (inter)national scientific consortium such as the Glioma Longitudinal AnalySiS (GLASS) consortium that investigates brain tumor molecular evolution and the Participant Engagement and Cancer Genome Sequencing (PE-CGS) consortium that directly engages patients in cancer genomics research.
