I'm a Senior Applied Scientist building production ML systems for diagnostics, reliability, repair recommendations, and hardware/signal decision-making.
🔗 john-hodge.com — projects, research, publications, and writing.
Current focus:
- ML for diagnostics, reliability, and repair recommendations on messy operational data
- Ranking, calibration, uncertainty, evaluation, and cost-sensitive decisions
- Multimodal modeling across logs, sensors, signals, and structured telemetry
Background:
- Ph.D. in Electrical Engineering with deep experience in RF modeling, phased arrays, antennas, and EM simulation
- Applied ML experience across production systems, transformers, Bayesian models, computer vision, and signal processing
- Interested in collaborations involving RFID, wireless inference, phased arrays + ML, signal/text fusion, and high-signal evaluation
