Yongzhao Wang

I am an assistant professor in the School of Computing at the University of North Florida. My research interests lie in Artificial Intelligence, with a particular focus on multiagent systems and their applications in finance and cybersecurity.

Before UNF, I was a research associate at The Alan Turing Institute in the UK, where I worked with Rahul Savani and Theodore Turocy. I received my Ph.D. in Computer Science from the University of Michigan, advised by Michael P. Wellman.

If you are UNF students and are interested in my research, feel free to contact me.
