About me

I’m Jiaxing Zhang, a Research Scientist at TikTok in Bellevue, WA.

I received my PhD in Informatics from New Jersey Institute of Technology in May 2025, where I was advised by Prof. Hua Wei and Prof. Michael Lee. I obtained my bachelor’s degree in Computer Science (Honored Science Program) from Xi’an Jiaotong University in 2020.

My research interests include multimodal large language models (LVLMs), graph neural networks, explainable AI, information bottleneck methods, and natural language/code analysis.

I actively welcome research collaborations across areas including (but not limited to): GNNs and their applications/explainability, LLM/VLM explainability and architecture optimization, training strategy optimization, video compression, and ML infrastructure. I’m also open to working with motivated, well-prepared interns.
