About

I am an M.S. student in Data Science at the University of Michigan, Ann Arbor, with expected graduation in May 2027. My research focuses on temporal point processes (TPPs), agentic AI, and diffusion models. At Michigan, I work with Prof. Raed Al Kontar on graph-aware monitoring and anomaly detection for LLM-based agentic systems, and with Prof. Qing Qu in the DeepThink Lab on diffusion models.

Previously, I worked remotely with Prof. Hongteng Xu at the Gaoling School of Artificial Intelligence, Renmin University of China, developing generative adaptation methods for TPPs that use conditional diffusion to generate context-specific LoRA adapters under distribution shift. I received my B.S. in Physics from Renmin University of China in 2025 and was a visiting student at the University of California, Davis in 2024.

Feel free to contact me if you are interested in related research or potential collaborations.

Research Assistant · University of Michigan · Advisor: Prof. Qing Qu

Investigating why autoregressive (AR) and random-order generation perform differently across datasets. This ongoing work develops a theoretical explanation and explores VAR-style training to identify generation orders best suited to AR modeling.

Generative Adaptation of Temporal Point Processes

2025.10 - 2026.03

Research Assistant · Renmin University of China · Advisor: Prof. Hongteng Xu

Proposed GA-TPP for zero-shot adaptation under distribution shift. Conditional diffusion generates context-specific LoRA adapters for a pretrained temporal point process, producing strong out-of-distribution gains on real-world datasets.

Deep Learning for Particle-in-Cell Simulation
