Zhuang (John) Liu’s interests include the role of the courts and judicial behavior, as well as law and development. He is one of the leading scholars in applying quantitative methods to analyze Chinese law. Currently, his research projects focus on utilizing a vast dataset of judicial opinions in China to examine and predict judges’ decisions; using statistical methods to estimate judicial transparency in China; studying law and development with a combination of court data and economic data in China; and conducting experimental studies to reveal the hidden behavioral patterns of judges. His work has been published in esteemed academic journals specializing in law and in China studies, including Journal of Legal Studies, Journal of Legal Analysis, Journal of Empirical Legal Studies, American Journal of Comparative Law, Journal of Comparative Economics, China Quarterly, and Journal of Contemporary China. In addition to his English publications, he also contributes to leading law journals in China.

He played a pivotal role in establishing the legal big data group at the Shenzhen Research Institute of Big Data, which conducts research utilizing extensive judicial decision data from China.

His current endeavors include the development of a comprehensive structural database of Chinese court decisions in civil, criminal, and administrative cases, facilitating empirical studies of the Chinese legal system. Additionally, he is constructing indices to measure judicial transparency and performance at the county or district level, a pioneering effort in this field.
