Summary
👤
Senior🎓
Top SchoolBrian Schaefer is a Senior Data Scientist with a decade of technical experience and 2+ years of focused industry work building algorithms that analyze hundreds of gigabytes of customer logs to detect cloud attack behaviors. He blends applied machine learning and large-scale data engineering to deliver timely, accurate threat notifications, and brings a rigorous experimental mindset from a PhD in physics where he developed instrumentation, data-acquisition software, and numerical models. At Cornell he published high-impact research on graphene sensors, mentored peers, and built open-source tools for modeling and visualization—skills he translated through an elite Data Incubator fellowship into production-ready NLP, Bayesian, and Spark solutions. Comfortable across research and applied product settings, he has a track record of improving device and algorithm performance by an order of magnitude and shipping end-to-end systems on AWS. Based in Somerville, MA, he’s equally fluent in low-level experimental systems and high-throughput cloud analytics, making him adept at turning noisy, complex data into actionable signals.
