Professor Jinjing Li holds a PhD in Economics, an MSc in Computing Science, and an MSc in Economics, and currently works at the University of Canberra. He is an expert in microsimulation modelling and serves as a board member of the International Microsimulation Association (IMA).

His research interests are at the intersection of public policy, simulation analysis, and health economics, focusing primarily on the impacts of social and economic policies on income distribution and public health. This multidisciplinary approach enhances understanding and addresses complex societal issues such as economic inequalities, health disparities, and social exclusion. Professor Li's research also reveals how tax and welfare policies alter income distribution patterns.

Using advanced statistical method like STINMOD+ for microsimulation and empirical dynamic modeling, Professor Li develops robust analytical frameworks for the field. These methodologies facilitate precise projections and analyses, allowing for more effective policy evaluations and adaptations.

In 2018, Professor Li provided expert testimony at the Senate Committee's Inquiry into the Treasury Laws Amendment on his tax simulation modeling work.
