The research team recruits several full-time postdoctoral/postdoctoral/research assistants throughout the year, and recruits graduate students who have been jointly trained in various forms. At the same time, we welcome undergraduate students from various disciplines in Sichuan University, as well as undergraduates from other colleges in Chengdu to do their graduation thesis or use their spare time to engage in research projects. In addition, the research team has long-term and stable cooperative relations with many first-class scientific research units at home and abroad, and can provide necessary recommendation and assistance for the study group members to study abroad, exchange abroad and insurance research. Interested students are welcome to make direct contact with Teacher Li.
