About Me

I am currently a Research Fellow at STEM, University of South Australia. Prior to this, I was a PhD student under the guidance of Prof. Xiaojun Chang at the University of Technology Sydney.

Research Interests

My main focus is on making groups of AI systems, or Multi-agent Systems, work more efficiently and effectively. I’ve put a lot of work into creating “MARLlib,” a toolkit that helps researchers like me find new ways for these systems to cooperate. It’s free for anyone to use and has become quite popular among people working in my field. My goal is to make AI research easier for everyone and to push the boundaries of what our technology can do.
