Neural signals flowing into a computational grid

Nathan Baune

Platform & Systems Engineer

I build production tools, ML systems, and complex software platforms — from real-time EEG classification and neuroimaging pipelines to a GPU-accelerated simulation engine with its own visual design environment, multi-language CLI, and LLM-powered natural language interface.

The thread connecting my work: studying how information processing architectures produce emergent behavior—from neural circuits to ML models to simulated ecosystems.

For the past decade I've built production systems in neuroscience and health tech:

  • Research tools and systems shipped to 9 labs across 3 institutions.
  • 2 startups: co-founder (PlatformSTL LLC), founder & principal engineer (Gothic Grandma LLC).
  • MR.Flow: GUI orchestrating neuroimaging pipelines with parallel execution optimized to user hardware. Setup and deployment reduced from weeks to ~45 minutes.
  • Epoche: ML workbench for neurophysiology—feature extraction, grid search, ensemble optimization, and interpretability tools for mechanistic hypothesis generation and model/ensemble deployment.
  • Real-time ML classification of brain state for closed-loop experiment control, therapy onset, and neurostimulation. <40ms end-to-end latency.
  • Proprio (PlatformSTL, St. Louis): STTR-funded wearable activity classification platform (hardware → cloud → ML pipeline) for monitoring patient care and long-term outcomes.
  • Countless rapid-turnaround prototypes and hours of engineering, scientific, and statistical consulting.

Current Interests

I'm actively exploring the intersection of AI and complex systems:

  • Agentic AI architectures — how multi-model orchestration, tool use, and planning emerge in LLM-based systems
  • Interpretability and alignment — making AI behavior legible and predictable, from SHAP/LIME to mechanistic interpretability
  • Simulation as testbed — using MUSE's transparent, deterministic systems to study how architectural choices shape emergent behavior
  • Human-AI collaboration — designing interfaces where AI augments rather than replaces human judgment (see: BABEL, Epoche)
