πŸ™ About Me

I'm a dual-degree Computer Science B.S./M.S. and Economics B.A. student at Yale University, building systems at the edge of autonomy, defense, and machine intelligence.

I design real-world ML systems that live on embedded hardware, control drones, detect gestures, navigate cluttered environments, and accelerate simulations. My work lives at the intersection of:

  • Edge AI & Robotics β€” quadrupeds, UAVs, and autonomous responders
  • Defense Systems Engineering β€” live-fire C2 simulations, counter-UAS optimization
  • Probabilistic Modeling & HPC β€” convex solvers in Rust, RAG pipelines, CUDA inference
  • Geospatial Intelligence β€” analyzing foreign energy infrastructure from space
