Summary
👤
Senior🎓
Top SchoolGeorge Tollefson is a PhD candidate in Pathobiology at Brown University and an experienced bioinformatics developer with eight years of cross-disciplinary work in genomics, clinical bioinformatics, and molecular biology. He builds and operates reproducible NGS analysis pipelines on HPC, authors user-friendly tools and packages (including VariantVisualization.jl and the VIVA executable), and applies novel algorithms for INDEL detection and alternative splicing analysis. His work bridges wet lab and computation—he has performed bench techniques, patient enrollment for large clinical cohorts, and led genotype-phenotype and transcriptomic studies that feed into manuscripts and clinical research. Based in Providence, he brings a practical focus on reproducibility, parallel processing, and translational impact, with a knack for turning complex genomic problems into accessible software for collaborators.
