About Me

Greetings! I am Keshu Wu, a Postdoctoral Researcher at Texas A&M University, working at the intersection of intelligent transportation, artificial intelligence, and cyber-physical systems.

I received a Ph.D. degree in Civil and Environmental Engineering from the University of Wisconsin–Madison. I also hold an M.S. degree in Computer Sciences from the University of Wisconsin–Madison, and an M.S. degree in Civil and Environmental Engineering from Carnegie Mellon University. I received a B.E. degree in Civil Engineering from Southeast University.

Research Interests
01Autonomous Mobility Intelligence

Higher-order multi-agent interaction modeling and relational reasoning; multimodal motion prediction, planning, and control; safety-critical decision-making and mixed-traffic intelligence.

02Agentic Mobility & Foundation Models

LLM/VLM-enabled reasoning and control; multimodal agentic systems; retrieval-augmented intelligence; generative and long-tail scenario synthesis.

03Spatiotemporal & Geospatial AI

Sparse-to-dense reconstruction and forecasting; higher-order graph/hypergraph learning; geospatial foundation models; multimodal sensing and data fusion.

04Digital Twins, World Models & Cyber-Physical Systems

Data-grounded and multi-fidelity digital twins; generative world modeling; physical–virtual closed-loop simulation; resilience and safety-critical stress testing.

05Connected & Cooperative Mobility Systems

V2X and air–ground cooperation; vehicle–road–edge–cloud intelligence; connected infrastructure analytics; distributed sensing, communication, and control.
