Summary
👤
Senior🎓
Top SchoolJohn Sigman is a Principal ML/AI Applied Scientist with 11 years of experience translating deep learning research into large-scale, production AI systems across healthcare, finance, energy, and defense. With a PhD in Electrical Engineering from Dartmouth and a postdoc in deep learning at Duke, he blends rigorous research (unsupervised domain adaptation, 3D volumetrics, Bayesian inference) with hands-on engineering—leading teams that build LLM-based RAG systems, self-hosted open-source models, and clinical/insurance generative pipelines. He has led diverse applied projects from biometric entity matching and vision-based particle detection to forecasting grid use and legal/financial document extraction, delivering in-production workflows at scale. Comfortable across firmware to cloud ML stacks, he also has a background in embedded imaging and electromagnetic sensing, which informs his practical approach to sensor and vision problems. Known to love Emacs, John brings both academic depth and pragmatic leadership to cross-functional teams driving ML from prototype to regulated deployment.
