About me

I am currently a Lecturer (eq. to Assistant Professor) in the School of Computing at the Macquarie University. Before that, I worked as a lecturer in the School of Information and Physical Sciences at the University of Newcastle, as a postdoctoral fellow in the School of Mathematics and Statistics at the University of New South Wales, and at Data61, CSIRO.

My Ph.D degree is obtained at the University of Technology, Sydney on May, 2015. Prior to coming to Australia, I received my Bachelor degree in Mathematical Statistics from the University of Science and Technology of China in 2010.

Research Scholarship Opportunities

I am looking for highly motivated and focused students with strong backgrounds or interests in Generative AI and large language models.

Available Opportunities:

• Demestic Research Scholarship Round (PhD & MRes) — Deadline: 31 October 2025

• International Research Scholarship Round (PhD & Master by Research) — Deadline: January 2026

• International Road to Research Scholarship (Master by Research) — Deadline: 31 October 2025

• China Scholarship Council (CSC) – PhD Studentships - Deadline: 16 January 2026

• Visiting Studentships and Research Internships

Research themes

Generative AI is my current research focus. I am leading the Macquarie Generative AI research group.

Also, I have extensive research experience in:

• Gaussian Processes

• Deep Generative Models

• Variational Inference methods

• Stochastic Point Processes

• Bayesian Nonparametric Space Partitions

• Markov chain Monte Carlo methods
