Summary

Senior🎓
Top SchoolElls Campbell is a Principal Data Scientist with 13 years of experience building production-grade ML and operational AI systems for regulated, mission-critical environments, currently leading AI at Leidos. They have end-to-end expertise across computer vision, NLP, and agentic LLM architectures, with proven deployments such as a YOLO-based TowerScout on CDC Azure that supports sub-5-minute field responder workflows. Ells blends technical leadership and product ownership—translating messy, high-stakes operational needs into defensible, auditable analytics used by federal responders and policy makers. Their work emphasizes robustness to real-world failure modes (data quality, seasonal drift, hallucination) through monitoring, retraining, and human-in-the-loop controls. A former CDC branch chief and bioinformatics lead, they combine deep domain knowledge in public health and bioinformatics with practical MLOps rigor. Colleagues rely on Ells for mentoring teams to balance innovation, regulatory alignment, and reproducible impact.
