+- **Machine learning** — order-invariant ICD-10-CM embeddings (under review at *JAMA Network Open*, deployed calculator), the NeuroPose 3D-kinematics system in Liqi Shu's lab at Brown Neurology, and ongoing research engineering at [NeuroAI](https://neuroai.health). Undergraduate work has been clinically focused; graduate study broadens the scope.
+- **Computer systems and high-performance computing** — the Weenix kernel, a TCP/IP networking stack from scratch in Go, and micro-architectural performance work (SIMD, hardware counters via PAPI, RAPL energy, cross-ISA ports across AVX2 / ARM NEON-SVE / RISC-V V) on Brown's OSCAR HPC cluster.
+- **Reinforcement learning and applied AI** — a Magic: The Gathering RL project on OSCAR; production agentic-systems work at xAI on `grok-code-fast-1`; reasoning, evaluation, and red-teaming contracts with Anthropic, Mistral, and OpenAI.
+
+Computer vision and security thread through all three but do not stand on their own.
