Hi! I’m Zhi.

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

My interests are agentic training (RL, Lean prover, search/play, ML system) and deep learning theory (representation and dynamics).

If possible, I would love to learn more about robotics and world models as well.

Publications

• 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.
