AI Race Coach (Project Koru)

Fri, 01 May 2026 00:00:00 +0000

The AI Race Coach (Project Koru) is a real-time coaching system for motorsports, developed during the Google I/O GDE Field Test at Sonoma Raceway. The project demonstrated how agentic AI can bridge domain gaps between software engineering and racing expertise.

Architecture:

Antigravity — stateful orchestration and telemetry ingestion
Gemini API — cloud-based driver modeling and strategic insights
Gemma 4 12B — on-device edge intelligence for zero-latency audio coaching
Jetpack Compose — high-refresh Android dashboard for real-time visualization
Google ADK — multi-agent orchestration framework
Custom USB Interface — 10 Hz telemetry stream wired directly from vehicle sensors to Pixel 10

The system identified performance gains beyond human perception — including a new throttle application zone mid-corner in Turn 2 that secured a 0.1-second advantage. Featured on the Google Developers Blog and covered in my blog post Racecraft: The Origin Story.

Edge Computing & Trusted Execution

Mon, 01 Jan 2024 00:00:00 +0000

This research area investigates how to bring secure, verifiable computation to resource-constrained edge devices:

Trusted Inference at the Edge — Combining smart contracts with trusted execution environments for verifiable edge inference (IEEE ICBC 2024).
Blockchain + TEE — Lessons learned from applying TEEs in blockchain applications, with implications for future secure systems.
Supporting Heterogeneous Infrastructure — Protecting critical infrastructure across diverse computing environments (AsiaCCS 2023).
AI-Based Personalized Interventions — Deploying AI models for health applications on edge devices (SynBio 2025).

This work bridges the gap between the security guarantees of centralized systems and the autonomy of decentralized, edge-deployed applications.
