Beijing Jiaotong University established its mathematics discipline in 1986, obtained the authority to confer master's degrees in Operations Research and Cybernetics in 1996, secured the right to award doctoral degrees in the second-level discipline of Operations Research and Cybernetics in 2003, and established a postdoctoral programme for the first-level discipline of Mathematics in 2009. Since its establishment, with strong institutional support, our Postdoctoral Programme has developed a comprehensive and well-structured management system covering postdoctoral recruitment, evaluation, and housing. It has implemented refined incentive mechanisms, with a special focus on fostering postdoctoral researchers' innovative capabilities and advancing digital infrastructure development. Furthermore, it has actively facilitated academic exchanges and international research collaborations, while providing systematic professional development programs to enhance researchers' interdisciplinary competencies. These concerted efforts have cultivated a supportive academic environment conducive to high-quality research and career development.

        From 2009 to present, a total of 17 postdoctoral researchers have been recruited. Since 2016, seven postdoctoral researchers have worked in the Programme consecutively, among whom five have been employed by Beijing Jiaotong University, one by the University of Science and Technology Beijing, and one is currently working in the Programme. One postdoctoral researcher, as a key participant, was awarded the first prize of the Natural Science Award by the Ministry of Education in 2018.

This Postdoctoral Programme has significantly contributed to the development of our university's mathematics discipline, talent cultivation, and scientific research endeavors. In recent years, our mathematics postdoctoral program has achieved substantial progress, making notable contributions to both academic research and social services. The key highlights are listed in the following aspects.

I. Discipline Development

        Since 2016, supported by the Postdoctoral Programme in Mathematics, our mathematics discipline has maintained its research-intensive and international orientation, achieving significant progress through reforms. The number of high-quality academic publications has continued to grow, and the discipline ranking has steadily improved: securing 38th place (top 25%) in the "2017 Best Chinese Subjects Ranking by ShanghaiRanking Consultancy" in mathematics; advancing from the top 350 in 2017 to the top 250 in 2019 in the "QS World University Rankings by Subject for Mathematics"; ranking among the global top 160 in Statistics and Operational Research in the 2021 QS World University Rankings by Subject. In the Fourth National Discipline Assessment, our statistics program received a B+ rating, while system science earned an A+. Additionally, the Systems Science discipline, jointly developed by the School, was selected for the national "Double First-Class" initiative. These achievements have made substantial contributions to Beijing Jiaotong University's goal of becoming a "world-class university with distinctive features".

II. Program Development and Talent Cultivation

        Supported by the Postdoctoral Programme in Mathematics, our Information and Computing Science program was granted national first-class undergraduate program status in 2019. Postdoctoral researchers in the Programme have actively contributed to curriculum development. Our Information and Computing Science program was established in 1999, and we are among the first ten universities in China to offer this discipline. Currently, the program boasts four student innovation labs, over 20 internship bases, and joint training partnerships with more than ten prestigious overseas universities.

        Over the past five years, the program team has engaged in extensive academic collaboration globally, jointly trained outstanding master's and doctoral candidates with institutions including Harvard University, Stanford University, the University of Minnesota, the University of Auckland, the National University of Singapore, and Loughborough University, and maintained regular academic exchanges and mutual visit programs with universities in such countries as Italy, Australia, the ROK, Japan, Singapore, and Israel.

III. Postdoctoral Talent Information Development

        The information management and service protocols have been implemented to maintain communication and information sharing with postdoctoral researchers after their departure. Since 2016, the Programme has hosted seven postdoctoral researchers who have achieved remarkable scientific accomplishments: four were awarded Postdoctoral Science Foundation General Grants, three received projects of the National Natural Science Foundation for Young Scholars, two led the general projects of the National Natural Science Foundation of China (NSFC), one received the Ministry of Education's Natural Science Award (First Prize), one was selected for the Beijing Young Talents Program, one was funded by the Xiangjiang Scholars Program, two secured China Scholarship Council funding for international visits, and one obtained full foreign sponsorship for overseas research. Other achievements include 1 granted invention patent, 43 SCI-indexed publications, and 1 monograph. Currently, two researchers have been promoted to associate professorships.

IV. Social Contributions of Postdoctoral Researchers

        Postdoctoral researchers leverage the strengths of our Department of Mathematics in operations research and cybernetics, applied mathematics, and statistical optimization to actively participate in interdisciplinary research. They have studied practical issues such as road network traffic (awarded the First Prize of the Ministry of Education's Natural Science Award in 2018), population genetics (developing new software to infer complex population admixture histories), and network information security (investigating pessimistic diagnosability and fault-tolerant diagnosability in various networks). These efforts have achieved promising results and produced positive effects in teaching (First Prize in the Beijing University Young Teachers' Basic Teaching Skills Competition).
