About

  • 🏥 Optimization intern at Memorial Sloan Kettering — GPU convex solvers behind radiotherapy planning (78 → 21 iterations, 3.7× faster)
  • 🔬 Graduate researcher at USC — LLM steering, speech models, RL agents
  • 📄 First-author paper at AIIDE 2026 (AAAI) · arXiv:2607.06854 · co-author preprint arXiv:2608.04669
  • 🎓 BS Computer Science, Sharif University of Technology
  • 💼 Open to full-time roles from Jan 2027, and PhD positions for Fall 2027

Research

  • 3D-DELTA — a 197K-parameter head steering MoE routing at inference with zero weight changes, 4× the SteerMoE (ICLR 2026) gain; transfers across four MoE families, 1.3B–30.5B
  • Adversarial Co-Evolution — masked PPO/TRPO against a gold-standard expert and distributed LLM opponents, on PettingZoo/RLCard · AIIDE 2026
  • Language-Agnostic SER — 6 speech encoders × 8 datasets; sparse autoencoders isolate 61 emotion features
