About me
I'm currently a Ph.D. Student at
The Department of Electrical & Computer Engineering at the University of Florida,
supervised by Dr.
Ivan Ruchkin who lead the Trustworthy Engineered Autonomy (TEA) Lab . I was tempororily in master program of Electrical and System Engineering at University of Pennsylvania. I received my B.S. degree in from Southern University of Science and Technology, China, where I was also a member of Pan Group@SUSTech
, supervised by Dr. Quan Pan who lead high-speed communication interface study. I used to be a member in
Brain-inspired Computing Lab
in Guangzhou Campus of Hong Kong University of Science and Technology (HKUST,GZ) for an internship with research direction of application of spiking neural network (SNN) and event camera, supervised by
Dr. Renjing Xu.
Research Interests:
-
Safe and Trustworthy Autonomous Systems: Modeling, analysis, monitoring and prediction; Confidence measurement
-
Time Sequence Prediction and Uncertainty Quantification: with ML/AI and foundation models (LLMs, VLMs and VLAs)
-
Representation Learning and Agentic AI: Casual/Physical-interpretable representation learning; World models

I am actively seeking to collaborate with researchers from a wide array of disciplinary backgrounds. My goal is to transcend the limitations imposed by conventional disciplinary paradigms by leveraging interdisciplinary perspectives. If you're intrigued by the prospect of working together to tackle complex problems through a multifaceted approach, I warmly invite you to reach out. Your expertise and insights could play a crucial role in our collective endeavor. Please don't hesitate to contact me if you're interested in exploring this collaborative opportunity further.
