Mark Jensen is a Director of Data Science with 15 years of experience building and managing genomic and bioinformatics data programs at the Frederick National Laboratory for Cancer Research. He has progressed through technical and leadership roles—spanning genomic data programs, data management and interoperability, to leading data science—bringing deep domain expertise in cancer and infectious disease data. Equally comfortable with code and strategy, he has contributed to core BioPerl modules and built production bioinformatics tools and Perl integrations for Neo4j, demonstrating hands-on back-end development and open-source stewardship. He also runs bioinformatics consulting projects and maintains publicly available tools such as a web-based S. aureus spa-typing app, reflecting a commitment to practical, reusable science software. Based in Rockville, MD, he pairs a PhD-level research background with decades of applied software engineering to turn complex biological data requirements into interoperable, production-ready systems. An often-overlooked strength is his sustained focus on tooling and parsing robustness—fixing low-level command-line and data-parsing edge cases that keep large pipelines reliable.
