Hi! I’m Zhi.

I am a PhD student at UC San Diego advised by Tianhao Wang.

I am interested in agentic training and inference (e.g. RL algorithms and LM post-training methods), AI for math (e.g. Lean prover training frameworks), multi-agent systems, and learning mechanics.

If possible, I would love to learn more about robotics and ML system/infra as well.

• Lee Eon, Andrés R. Vindas-Meléndez, and Zhi Wang. Generalized Snake Posets, Order Polytopes, and Lattice-Point Enumeration. Discrete Mathematics (2026): 115072. We derived the Ehrhart and h-star polynomials for the generalized snake posets, with closed-form formulae for the two extreme cases, and obtained a monotonicity result using a novel technique that bridges combinatorics and lattice polytopes, extending several previous results.
