Rockstar🎓
Top SchoolMatthias Zepper is a bioinformatician and systems developer with 10 years’ experience building reproducible analysis pipelines and infrastructure for high-throughput sequencing at SciLifeLab in Stockholm. He combines deep computational biology training (Dr. rer. nat.) with hands-on software engineering, contributing backend fixes and new modules to prominent open-source tools like MultiQC to improve error handling and data aggregation across large sample sets. Matthias has startup experience exploring cloud data engineering and novel ways to marry DNA-driven workflows with modern storage and ML architectures to close the “digital divide” in molecular biology. His background spans academic tumor biology research, scientific/regulatory medical writing, and production-grade core-facility software—making him fluent at translating complex life-science problems into reliable, scalable software solutions.
