About

Hi! Welcome to my website. I’m Qiong (pronounced similarly to “Chiong” if that helps!).

I am currently an assistant professor in the Division of Computing and Mathematical Sciences at Mohamed bin Zayed University of Artificial Intelligence (MBZUAI). As a statistician by training, I have ventured into the world of AI, exploring how data and algorithms can unravel complex stories. My research bridges statistics and machine learning, with a focus on mixture reduction, empirical likelihood, and tabular foundation models for in-context learning. See a detailed description of my current research directions here.

I am passionate about addressing real-world problems through statistical and AI-driven approaches, and I believe that data is the most compelling storyteller of all. If you’d like to chat about statistics, AI, or the hidden narratives within your dataset, I’d be delighted to connect!
