UCLA Moonshot Math Harness

Research Assistant · Prof. Kai-Wei Chang, Nanyun Peng, and Terence Tao

Built a long-horizon multi-agent reasoning harness that has solved multiple open mathematical problems, orchestrating specialized explorer, verifier, and consultant agents with a rich library of skills and MCP tools. The harness statically enforces each role's capabilities.

Designed persistent graph-based memory to preserve intermediate results and competing proof directions across long-running executions. Self-evolving memory curation and iterative planning prioritize high-value branches and adapt the problem-solving strategy; co-first-author paper in submission to ICLR 2027.

Built a privacy-preserving safety guard for LLM multi-agent systems using an edge-featured graph attention network trained through federated learning without sharing raw interaction traces. The 0.5M-parameter, approximately 50 ms CPU sidecar outperformed the centralized-training ceiling on three benchmarks and reduced live attack success by 43% at above-unguarded utility. Amortized MAS topology design into a 16-entry VQ-VAE codebook with a reward-weighted code predictor and an execution-grounded MLP reranker, achieving the best accuracy across all six benchmarks (84.6 vs. 83.0), over 120x faster design at 2.4 ms, and 21.9-33.2% fewer LLM tokens; both first-author papers are in submission to AAAI 2027.

SCAI Lab UCLA

Research Assistant · AI and Data Mining

Developed Gaussian speculative decoding in PyTorch using lightweight draft models and single-pass parallel verification, accelerating pretrained time-series foundation models by up to 3.1x across five model families without retraining. Proved a capped-geometric throughput law to predict speedups before deployment and a bounded-deviation guarantee on forecast fidelity to the target model; first-author paper submitted to AAAI 2027.
