NEXZ AI Lab
We work on building affordable, robust, and scalable medical AI co-pilots that can trustworthily perceive, reason, reflect, and act in complex clinical environments, with recent focus on world models, multimodal foundation models, continual learning, self-evolving AI, label-efficient learning, and agentic AI systems for healthcare applications.
Note: I will join Tongji University (Shanghai, China) as a CS faculty member, and I am recruiting Ph.D. and master's students for Fall 2027, as well as postdocs/RAs on a rolling basis. You will work closely with our international team from, e.g., Stanford, Harvard, MIT, Columbia, CUHK, HKU, NUS, Tsinghua, Alibaba DAMO, Ant Group, and Tencent. If you are interested in cutting-edge topics in AI+X (e.g., healthcare and robotics), feel free to reach out with the email subject [PhD/Master/RA Application]. Applicants from top universities in mainland China are especially encouraged to apply.
