Hi there 👋

I'm currently a CS PhD student at Michigan State University.

Research & Projects

1. DL Infra, Agent, Long Context Modeling (2026-present)

Currently working on new directions.

Projects

• Auto Reader: Automatically paper reading and note taking
• Slack GPU Monitor: A slack bot to manage your server's GPU.

Writings

• A tutorial on DL Infra (Chinese version)
• Notes on optimization

2. Relational Deep Learning (2025-present)

• AutoG: Towards automatic graph construction from tabular data Zhikai Chen, Han Xie, Jian Zhang, Xiang Song, Jiliang Tang, Huzefa Rangwala, George Karypis; ICLR 2025 (poster) Code
• A Pre-training Framework for Relational Data with Information-theoretic Principles Quang Truong, Zhikai Chen, Mingxuan Ju, Tong Zhao, Neil Shah, Jiliang Tang, NeurIPS 2025
• Relatron: Automating Relational Machine Learning over Relational Databases, ICLR 2026 Zhikai Chen, Han Xie, Jian Zhang, Jiliang Tang, Xiang Song, Huzefa Rangwala (camera ready and code coming soon)
• Relational foundation model (a library and a pre-trained model, stealth mode)

3. Graph Foundation Models and Large Language Models (2023-2025)

Note: In the past, I worked on graph foundation models (especially on text-attributed graphs) for a while, these related libraries won't be maintained any more. I personally don't recommend newcomers working on these settings and datasets.

• Graph Foundation Models Haitao Mao*, Zhikai Chen*, Wenzhuo Tang, Jianan Zhao, Yao Ma, Tong Zhao, Neil Shah, Michael Galkin, Jiliang Tang 2024 [Paper lists]; ICML 2024 (Spotlight); * means equal contribution
