Senior🎓
Top SchoolPoshen Lee is a Senior Applied Scientist with 11 years of experience applying ML/AI to cybersecurity, currently advancing Cloud SIEM capabilities at Datadog after leading generative AI and graph-based detection work at ExtraHop. She has deep expertise in recommendation systems, link prediction, time-series anomaly detection, and agentic AI that automates vulnerability-to-detection mapping and translates natural-language analyst queries into validated API searches. Poshen built production DNNs and high-performance microservices that scale across hundreds to hundreds of thousands of entities, and authored early cyberattack pattern models that process millions of detections monthly. Her background combines a Ph.D. in ECE with hands-on engineering across research labs and industry, enabling her to bridge novel research (e.g., VizioMetrics) with production-grade security products. An often-overlooked strength is her focus on operational tooling—prompt optimization ecosystems and introspective feedback loops—that measurably improve model utility and analyst productivity.
