About

Portrait of Tianyi Zhang

I’m a master’s student in computer science at Georgia Tech, graduating in May 2027.

Most recently I worked on LLM-based retrieval at LinkedIn. Before that, at GT EIC Lab × NVIDIA AI Research, I helped build tools for evaluating agents and auditing benchmarks. My research began at Emory, with directed and time-varying brain networks.

My interests are representation learning, LLM post-training, and model and agent evaluation. I’m particularly interested in how models learn from sparse or noisy feedback.

    NVIDIA’s framework for LLM post-training and RL; my work is on training efficiency and correctness.

    • Cut unneeded compute and communication in log-prob and top-k distillation.
    • Worked on multi-reward GDPO in the async training pipeline.
    • Worked on streamed PPO minibatches to lower memory use.

Personal

Away from work: photography, mountains and rivers, animals, travel and music. I am slowly learning the guitar.
