Jingsong Jason Liang

I am currently a research staff at the National University of Singapore (NUS), working with Prof. Guillaume Sartoretti at the Multi-Agent Robotic Motion Laboratory and Prof. Rodney Teo at the Temasek Laboratories. Before that, I received my master’s degree in computer science from the National University of Singapore and my bachelor’s degree in electrical engineering from Northeastern University.

My research focuses on generative and foundation models for cooperative multi-agent learning. I also work on multi-robot systems and autonomous robotic exploration, navigation, and coverage.

Happy to chat more about relevant research topics and collaborations!
