Ben Johnson, Ph.D.
Biography
Dr. Ben Johnson earned his B.S. in biology from Calvin College and his Ph.D. in microbiology and molecular genetics from Michigan State University. His graduate work focused on developing chemical probes to dissect molecular mechanisms of environmental sensing and adaptation in Mycobacterium tuberculosis (TB), with the ultimate goal of identifying new therapies against TB infections. The small molecules identified often would not directly kill TB in vitro and instead acted as anti-virulence compounds, disarming the pathogen during infection. Thus, computational biology approaches were used in conjunction with “wet” experiments to narrow down putative pathways altered in response to treatment with these experimental compounds to generate tractable hypotheses. Following graduate school, he worked as a bioinformatics research scientist in the Bioinformatics and Biostatistics Core at Van Andel Institute doing sequencing data analysis. In 2019, he joined the laboratories of Drs. Tim Triche and Hui Shen as a postdoctoral fellow.
Current research focus
Optimization of whole-genome bisulfite sequencing from low input single-cell and cell-free DNA. This technique will be a powerful method to study DNA methylation changes in cell transformation during tumor progression (single-cell level) and to detect DNA methylation changes in cancer patients’ plasma to serve as biomarkers in early tumorigenesis detection.
