Summary
👤
Senior🎓
Top SchoolAles Varabyou is a Senior Scientist and computational biologist with 11 years of experience building open-source software and scalable pipelines for large-scale genomic and transcriptomic analysis. He designs high-performance tools in Rust, C++, Python and SQL to scale RNA-seq and comparative genomics from single samples to hundreds of thousands, and has led projects such as TieBrush, ORFanage, and CHESS 3 that improved gene catalogues and isoform resolution. His work spans human and viral genomics, including pangenomic HIV-1 analyses and BoloTie, the first method to detect recombinant SARS-CoV-2 lineages from mass sequencing data. Based in Baltimore, he combines rigorous academic training (PhD in Computational Biology, MS in Computer Science) with production-oriented engineering at institutions like Johns Hopkins and PacBio. Notably, he focuses on practical open-source methods that make large-scale, reproducible comparative genomics accessible to the community.
