About Me
I'm a Tenure Track Assistant Professor at the Department of Computer Science at Rutgers University-New Brunswick. I earned my Ph.D. in Computer Science from Rice University under the guidance of Dr. Xia Hu. I received my B.S. in Automation from Tsinghua University, where I was advised by Dr. Jiwen Lu.
Our research focus is in the realm of Trustworthy Machine Learning, a critical area that demands the infusion of trust throughout the machine learning lifecycle—from data acquisition and model development to deployment and user interaction. Within this overarching theme, I specialize in issues related to robustness, fairness, and explainability. Additionally, I collaborate closely with health informaticians from New Jersey Medical School, UTHealth, and Baylor College of Medicine, leveraging machine learning to address critical challenges in healthcare.
The Large Foundation Models (e.g., large language models, vision-language models, and vision-action models) bring new and complex challenges to the trustworthiness of machine learning. Our long-term objective is to develop computational regulatory frameworks for these generative machine learning systems to prevent potential misuse and ensure their responsible utilization.
🔥 I’m always looking for outstanding PhD students and research interns. If you’re interested, please email me with your CV, transcript, a summary of your research experience, and highlight publications. I will carefully review every application.
