About me

Hi! I’m Xueqi Cheng, a Ph.D. student in Computer Science at Florida State University, advised by Dr. Yushun Dong in the Responsible AI (RAI) Lab. My research aims to enhance the utility, security, and efficiency of Machine Learning as a Service (MLaaS), with applications ranging from graph-based learning to natural language processing and computer vision. I am also broadly interested in social network analysis and AI for social good, focusing on how AI can help address key societal challenges.

Feel free to drop me an Email if you are interested in collaboration!
